ABSTRACT: Principles of the theory of pulse linear systems with variable
parameters are considered. The concept of impulse reaction of the continuous
part of the system underlies the theory of both variable -parameter and constant-
parameter systems. The impulse reaction is considered here as a function of
two discrete variables: the present time coordinate and the pulse application
duration. Methods of determining the pulse-system characteristics as
functions of various parameters are presented, methods of finding the system
reaction on the basis of such characteristics are indicated, the variable-

ABSTRACT: It is shown how the stability conditions for a constant-parameter pulse
system can be extended to cover the case of var'6able-parameter systems.
In order to analyze the stability of a variable.-parameter system having a
pulse feedback, the transfer function of that system is deduced. The find..rgs
are Illustrated by an example of a pulse-feedback system with a pass
repetition-rate modulation which has some applications in radio engineering.
A linear variable-parameter pulse system is a two-elemee. system whose first,
"pulse" element converts a sontiwaous input stimulation Into a series of
pulses which are amplitude-modulated by the stitwilation; the second element,
is a "linear circuit". Properties of a varlablo-parameter pulse system are
determined by these characteristics: pulse reaction, transfer function, and
frequency characteristic. The Irarpose of the article Is to find mathematical
conditions under whigh the lariablo-parameter pulse system is stable.
A linear variable-parameter pulse system may be considered as stable if its
reaction to any limited Input stimnlation will also be limited (subhead 2 of
the article). The above condition follows from an analysis of the finite-
difference equations which describe such systems. It is easier, however, to
Card 1/2

arrive at the stability conditions by a simple extension of the stability
criteria which are used for ccn3tant-rarameter systow. A mathematical treatmant
follow along the lines of that givon by Samoa, Viculs, and Philips (Ref 3).
The mathematical condition for stability of a variable -paraw t or pulse lystom
is thia: At any moment n the tran-sfez- tlmatioa 11(q,n) will have -no pz.-les in
the right semiplane or on the imaginary axis of the q-plane if the hodograph
of the frequency characteristic H(jx,n) , vulth z being within the range of -Ir
to +_Tr, does not embrace the origin of coordinates. Such an appivarh to the
analysis of stability is particularly expedient in case of a pulso-backfeed
system. As the analysis of stability of a 7artable-paramter Irilse syst-.9m with
a pulse backfeed requires the knowledge of Its transfer funation, a deduction
of the latter is offered under the subhead 3 of the article. A finite-difference
equation for an open pulse system is developed, and the transfer function is
found in the first approximation. In conolusion, a pulse-backfeed system with
a variable pulse rate is cansilezy3d. The differeatial equation of the "linear"
section of the system is solved for a particular practical case of pulse repsti-
tion-rate modulation. Use of the repetition-rate characteristic hodograph in a
stability analysis is demonstrated. Theie are four figures and five refereaces,
three of which are Soviet and two American.

ABSTRACT: The work deals with the analysis of random processes in
linear systems, in which the input signal is in the form
of a train of rectangular pulses. The amplitudes of the
pulses and their repetition period T oh and their duration
To, are (in Cieneral) variables and the laws of their
variation can be represented as random or regular (non-
random) processes. The Darameters of the linear systems
can also be variable and can be descrj-bnd either by random
or regular time functions. In the analysis of such systems,
it is possible to employ the concept of a pulse system
consisling of a pulse element and a linear section
(Figure 1). It is assumed that the input perturbation

by means of the pulse element; the resulting signals
'BXJJ(t) are applied to the linear section. The problem of
determining the statistical characteristics of non-stationa y,
discrete, random processes at the output of a pulse system
with variable parameters can be solved by means of the
theory of canonic representation of random processes, as
proposed by V.S. Pugachev (Ref 5).A discrete, random
function;, u(n), can be characterised by its mathematical
expectancy and its correlation function. The mathematical
expectancy is expressed by;
+00
M (n) = M(U(n ufl(u, n)du 1)/
u JI =
-00
where fl(p, n) is a uni-dimensional, differential,
probability distribution law. The correlation function is

where U, dom, non-correlated quantity Eaving

correlation function by Eq.(?), rhere the quantity S(x)
can be found from Eq.(8), in which 6(x) is the Dirac
function. For the stationar , discreteltLndom functions,
u(n) can be written as Eq.(95 and the correlation function
as Eq.(10). If it is asoumed that the input perturbation
and the variation of the parameters of the linear system are
independent and that the input perturbation is a quasi-
stationary, random, discrete process, this can be expressed
in the canonic form by Eq.(11), where a and M are
slowly changing functions of n ; the canonic represen-
tation of the correlation function * iv n by Eq.(12),
where S and U are related by Eq.(8 . The character-
istics of a pulse system with variable parameters can be
described by a frequency characteristic H(jx, n) or by an
impulse characteristic Hl(.4 , n) . Consequently, if the
input signal is in the form of Eq.(11), the output sional
L,
is given by Eq.(14); this can be approximately represented
by Bq.(16). The mathematical expectancy of the output
signal is expressed by Eq.(18) or, if the parameters underL:o

'variable Parameters
The correlation function for the output signal is des-
cribed by Eq.(31). If the parameters of the system vary in
a regular manner, the correlation function is given bj Eq.(32)
Formulae (18) and (31) can be used to analyse the response
of a pulse system with variable parameters- When the input
signal is in the form of a stationary, random, discrete
processl the output expectancy is given by
Eq.(35) and the correlation function by Eq.(36). If the
variation of the parameters of the system is also in the
form of a stationary process, the expectancy and the
correlation function are given by Eqs.(37) and (38),
respectively. For a pulse system with constant parameters,
the correlation function is given by Eq.(39). The average
value of the correlation function of a non-stationary,
discrete process at the output of a pulse system with
variable parameters can be found from Eq.(43). If the
parameters of the system undergo a regular variation (in
particular, periodiciariation) and the inout signal is a
stationary, random process, the average value of the cor-
Oard5/7 relation function is expressed by Eq.(4?). The above

formulae can be employed to analyse the performance of a
Dulse-frequency modulation receiver, when the input signal
consists of pulses and noise. The receiver consi-sts of
a linear amplifier baving a gain KO I a demodulator with'
a time constant T and a gating circuit. It is assumed
that the repetition frequency of the pulses is expressed
by Eq.(49 so that the frequency characteristic is given
by Zq.(O (Ref 2), where h , a and 0 are expressed by
Eq.(51) and 1 0 and 11 A the modified Bessel functions.
On the basis of Eq.(20), the mathematical expectancj of
the output signal is expressed by ]5q.02), while on the
basis of Lrq.(32), the correlation function is given by
mq.k54), where functions f and ~o are defined by Eqs.(55).
The dispersion of the output signal is defined by Lrq.(56) and
the average value of the correlation function is given by
Eq.(58).

ABSTRACT: It is shown that with sufficiently wide assumptions the
pulse detector is equivalent to a linear pulse circuit
and therefore can be characterized by a transmission
function. The formulae obtained for this function permit to
determine the reaction of the detector to a random regular
series of Dulses for which the demanded restrictions are
satisfied by means of the equations deduced here, (8) and
(9) (or (10) and (11)) the values of the detector output
voltage U2(t) can be determined at the moment of the
formation or the ending reps. of pulses. As the found points

curve sections the curve U 2(t) can oasily be found. The
transmission function of the pulse detector makes it
possible to find also the statistical characteristics of the
random process at the output according to given statistical
characterstics of the process at the detector input.- Then
the pulse detector is investigated under the influence of a
series of pulses modulated by a steady random process. The
formula (22) for the spectral density F(x) is deducedw This
spectral density of the random process at the output of the
pulse detector is equal to the product of: 1.- The density of
the discreet steady random process at the input.-
2.- The square of the modulus of the detector frequency
characteristics and 3.- The energy spectrum of the "pulse" of
the single amplitude, the duration T (sequence period)
and one form limited by two exponentfal sections. From this
follows that the spectral density of a discreet random process
coincides with an energy spectrum of a sequence of 6-functions
(of practically v'ery short pulses) which are modulated accordrg
Card 2/3 to the correspondine law. Finally the opectral density of the

process at the pulse detector output is investigated with
a simple form of the process correlation function at the
input. The formula (29) obtained here can physically easily
be understood when the equivalence of the pulse detector
with the pulse circuit with a linear part in form of an inert
member is taken into account.

TITLE: Frequency-modulated range finder in the presence of
noise and reflected signal fluctuations
PERIODICALt Radiotekhnika i elektranika, Vol.6, No.4, 1961,
PP. 536-544
TEXT: The author considers the operation of a frequency-
modulated range finder in the presence of noise and fluctuations
of the reflected signal, i.e. operation under real conditions.
After an involved analysis, he finds that under the usually
pertaining relations among the parameters, the errors of such
systems are very small. At the same time, where needed, further
improvements over existing systems may be obtained by including
variable narrow-band filters in the system, with the center
frequency variable according to the distance being measured.
Acknowledgements are expressed to V.G. Repin for valuable remarks

ABSTRACT: The follovii4g empirical equation is proposed for component wear as a func-
tion of time under normal operating conditions:
t=A1 h+5
-h+60
,_.,,.v~ere t is the operatin4 period for the component in hours,,kilometers or other units,
'J~is the durability fac r expressed in the same units, h is the displacement of the
00
e from the nominal line with a reverse sign, and 6 and 60 are the current and
jaricurv
it al deviations of the dimensions of the component from nominal. Norma.1 wear con-
ditions are described by this equation when the coefficient A has a positive value
(figure 1), while a negative value for this coefficient corresponds to break-in con-
ditions (figure 2)-. Curves are given as well, as modifications of the basic equation

describing the variations in the distribution of devia-
tions in the dimensions of the component after opera-
tion for a given time under four sets of conditions:
1. wear during the break-in period where a change in
clearance between components has no effect on the rate
of wear; 2. wear during the break-in period where there Figure 1 t
t
is an optimum clearance corresponding to minimum wear;
3. wear under normal operation with an extermely brief
break-in period; 4. wear in the case where there is a
transition from the second type of break-in period to
normal wear, so that one part of the initial distribu-
tion lies below the asymptote of the curve for normal
wear, while the other part lies above this limit.
Necessaz7 conditions for reliable statistical results t
are discussed. A method is proposed for statistical Figure 2

ABSTRACT. The vibration packing of a I -component systen of spherical powd;rs has
been investigated. Experimental data on the effect of the frequency and amplitude
of vibration on the rate of packing and the attained density are presented. The
optimal operating conditions are determined. It is also shown that the maxi

diagram of the test device is shown. Test measurements are plotted to portray the
variation of powder briquet density as a function of vibrational frequency and
amplitude, and as a function of static pressure, The studies showed that for alloys
VK-6 and VK-20 higher densities are obtained with greater vibrational amplitudes.
In the experimental conditions for this series of tests frequency was not found to
have an appreciable affect on the consolidation process. There is an upper limit of
amplitude; above this limit value the triqueto may be destroyed* Vibrational
consolidation increases with higher static pressuress howevert the intensity (rate)
of densification decreases with increasing static pr6seures The results show that it
may be feasible to use electromagnetic vibrators for 'industrial production of the

-0416 + 0#1 mm fraction, 5.26 g/cm2 (the initial loose-powder density.
Iwas 4.6-4.7 g/cmZ), was obtained with vibrations at a frequency of
1100 cps and an amplitude of 5 u. Each lnvestL&ated powder fraction 4'
attains the most intense compaction in its ova specific band of
optimal amplitudes and frequencies. At a constant vibration ampli-
tude, both the deneLfication rate and the density increase with in-
creasing frequency and reach a maximum at optimal amplitudes whose
magnitude decreases with increasing frequency. For the -0.16 + 0.1 mm
fraction at a*vibration frequency of 50 cps, the optimum amplitude
e was 10-30 u.-- Vibrations at higher than optimum amplitudes
rang
le'd to loosening. Under identical vibration parameters the density
of coarse powder was higher than that of fine powder. Also, in the
range of optimal amplitudes the time required to obtain a given
density decreased with increasing (within definite limits) frequency.
:The general conclusion is that densification by vibration offers
idefinite advantages in maLing filters and other porous parts from

Abstract The efficiency of periscopic antennas was studied for the case of uneqgal
diameters and for shoft distances between the mirrors of the radiator and
of the re-radiator, when the'wave reflected from the re-radiator (flat mir-
ror) is not Plane. The calculations were mad for the axially-symm Itr-,Ic&l
problem in the Kirchhoff scalar approximation, using the aper4ture method.
The radiatoit and re-radia~or are replaced in the calculation by round aper-
tures, as is custoiarily done (Ref. Zhur. Fiz. 1.954, 1890). The wave in the
aperture corresponding to the radiator is assumed to be plane with an axia-Uy-
symmetrical drop-off*:Un the amplitude toward the edge of the aperture, using
the law 1 - A (r/1)2,,where r is the running radius and 1 the radius of the
aperture. The expression for the field at infinity is *Fitten in terms of a
Lommel function (in the form of series of Beseel functions). The phape of the
integrand of the approximation is approximated by a quadratic expression,

calculations are the ratios of the diameters of the radiator and re-radiator;
the coefficient characterizing the decrease in the amplitude, and the di-
mensionless parameter m = 21rfla~j- d) where a is the radius of the re-radi-
ator aperture and P the coefficient in front of the quadratic term in the
texpression for the phase of the integrand. The maximum efficiency of a
periscopic system, calculated,as the ratio of the square of the field in-
tensity of the entire system to the square of the field intensity of the rac-
diator'is obtai4ed when 1 < 1, i.e., when the mirror of the re-radiator is
gepater than the mirror iTf t~e radiator; this ratio, other conditions being
equal, is grbater for41minibhing distributions at small values of m (large
distances d). it is-noted that the intrqAuction of an other than TiTylor ex-
pansion for the phase of the integrand ((.5# 1) affects little the value of
the efficiency, but makes it possible to use the equation for Muth larger
values of a/d., i.e., for cases when the distance between the radiator and the
re-radiator is merely 2-3 times greater than the diameter of the mirrors.

ABSTRACT: It was shown earlier (Ref.1) that the electrodynami,
field of a system can be expressed by mean of Eqs.(3), in
which the function f should satisfy an electrostatic differe-
ntial equation expressed by Formula (2). This method is
applied to the evaluation of the field produced by a wedge
formed of two ideally-conducting semi-planes (see Fig.1).
The larger angle between the planes is 6 and it is assumed
that the axis z cdneides with the edge of the system. If
an electrostatic charge q is situated at a point Mo I
having cylindrical co-ordinates z0 = 0 7 Ro = I and go = 6/2
the electrostatic field potential can be expressed by Eq.(4),
where Tr/6 For small the iRtegral of Eq. (4) can be
written as Eq.(5). If the product qL is maintained constant
U,,dl/,and equal to p0 when 0 , the potential can be expressed

by Eq.(?). If the cylindrical co-ordinates are changed into
spherical co-ordinates, -Bqu.(?) can be expressed as Bq.(8),
so that the function f is given by Eq.(~). In the solution
of the dynamic problem, it is assumed that the Ifertz dipole
has a moment as expressed by Eq.(12), in which 1 0 is the

ABSTRACT; The known theory (Refs 1-4) deals with the directivity of a
linear radiator which is in the form of a set of similarly
polar4sed monochromatic sources ofYgiectromagnetic field;
the sources are either continuously or discretely distri-
buted over a region such that the deviations of all the
points from the axis of the system are small in compariso.,.~
with the wavelength (see Figure 1). The theory shows that
a linear radiator is characterised by a scalar function
IW which describes the distribution of the phase and
amplitude of the currents or the fields. The field of the
radiator for r >> L can be described by one of the
following formulae:

problem of a linear radiator and that of a non-uniform
line are analogous. The problem of a linear radiator is
dealt with in some detail. It is shown that the so-called
super-directive distribution of sources can be derived) but
this cannot be realised in practice. The synthesis can be
carried out approximately by using the so-called iterative
method which permits the expansion of the given directivity
function into two components: 1) a function which can be
realised by sources situated within prescribed limits and
2) a function which can be realised by employing radiation
sources situated along a straight line outside the radiato-r.
It is shown that in two practically important cases, the
iterative method does not require complex calculations.
In the first case, the maximum of the modulUB Of the deriv-
ative of the complex directivity pattern 'which is given
by an analytical expression does not exceed the ratio of the

problem of wide-band matching of the loads which have a
large phase component of the reflection coefficient. Here,
it is shown that it is comparatively simple to estimate
the maximum possible approximation and the realisability

ABSTRACT: An ideally conducting, infinitely thin paraboloid of
revolution is considered. A spherical system of co-
ordinates, having its origin in the focus of the
paraboloid is introduced. The axis OZ (Figure 1)
coincides with the axis of revolution. The co-ordinates of
the point of observation are denoted by R, 0 and 9
while the co-ordinates of the integration point on the
m.i.rror are R', ()' and y' The equat�on of the para-
boloid is given by:

from Eqs (2), where the index 0 denotes unit vectors.
On the basis of the aperture method of analysis, the field
in the mirror can be determined from Eq (4). Consequently,
the directional pattern of the miiror is given by Eqs (5),
where Ic = 2tt/7, . The current at the surface of the
paraboloid is given by Eq-(6). By integrating Eq (6), it
is possible to find the vector-potenti~al and its trans-
verse components which coincide with the transverse
components of the electric field in the far zone. These
are given by Eqs (7). By comparing Eqs (5) and (7), it is
seen that the field calculated by the second method
differs from the field evaluated by the aperture method.
In particular, the difference in the second method lies in
the non-linearity of the phase function. The aperture
method is applicable at small angles of the observation
point and the condition of applicability Is defined by
Eq (10), where n is contained between 0 and I and
depends on the geometry of the mirror: 81,P denotes the
Card2/4 minimum angle inside the boundaries of the mirror. When

the mirror is axially symmetrical. its directional
pattern can be expressed by Eq (11), where function
f(t) is Imown. Eq (7) can, therefore, be written as
Eqs (12) and (13) where a = tfD/X is the ]mown parameter
of the aperture method. If only the scalar directional
pattern is of interest, the field can be represented by
Eq (14). If the function f(t) = (1 _ t2)n , the structure
of the side-lobe radiation can be investigated by employing
Eq (14). This leads to Eqs (16). These can approximately
be represented by Eqs (17). Eqs (16) and (17) become
identical for 0 = I The formulae were used to plot a
number of directional patterns for a mirror having an
aperture of IOX . The results are shown in Figures 2, 3
and 4. The results obtained by the aperture method are
illustrated by the 'dashed' curves, while those evaluated
on the basis of the second inethod are represented by the
solid curves. From the analysis it is concluded that the
second method of calculating the directional pattern of
parabolic antennae permits the evaluation of the nearest

ABSTRACT: The purpose of the present article is to study the error
,-6f the current method of calculating reflector antennae
and to estimate the possibilities of making it more
exact. The current on the reflector surface is assumed
to be.a function of the coordinates of the reflector
Point projections of the focal plane. The approximation VI/
adopted in the current method involvea three errorst
the field established by the exciter is substituted by
its asymptotic representation neglecting the near field
of the exciter; interaction of the currents in diff9rent
parts.of the surface isneglected; the interaction of
currents flowing over the shadow side of the surface and
Card the perturbation currents of the reflector edge on the
1/2 illuminated side are neglected. These approximations
are:usually justified by the large value of the parameter

FA. The effect of the exciter near field is first
S-tudied. Its.effect increases with increase of
dimensions or exciter directivity. The affect of
reflector curvature Is then analysed by a method of
successive approximations, It is found that this effect
is negligible in comparison with the contribution of the
exciter near field. Its effect reduces.to the appearance
of a.constant phase shift in the current distribution.
The edge effect is then analysed. With zero excitation
of the reflector contour it is necessary to take into
account the currents induced on the reflector contour by
the excited near field. The exciter near field is
directly expressed through its directional pattern but
has a different distribution at the reflector. The ratio
of current induced by this field to that established by
the radiation field of the exciter is equal in order of
Card magnitude to the ratio of exciter and reflector diameters.
2/2 The effective zone of action of the edge effect is of the
order of tenth wavelength.

TITLEa Radiation of a Reflector Antenna in the Shadow Zone
PERIODICAL: Radiotekhnika i elektronika, 1966, Vol-5, No.9,
PP.1398--i4o6
TEXTs The article is based on the current method of
calculating reflector antenna radiations. The reflector is
assumed to be ideally conducting and infinitely thin. with a
low-direetivity radiator. The radiator dimensions are assumed
comparable with the wavelength and small in comparison with the
reflector dimensions. The analysis takes into account diffraction
correction for the radiator near field, curvature of the reflector
and edge ef'Pect, discussed in Ref-3- The radiation of the
reflector antenna in the shadow zone is determined by the
screening effect of the finite metal reflector and depends little
on the directivity of the antenna. It is defined 1) by the field
of the .-adiator and the character of the radiating points on the
reflector boundary; 2) by the distance from the stationary point
of the reflector to the radiating point on the boundary and
3) by the presence of the edge effect at the sharp edge of the

reflector. When the reflector boundary is intensely
irradiated, the shadow zone field, calculated without considering
diffraction currents can be made more exact by taking into account
the edge effect. Regardless of the distribution of radiation
from the primary radiator, at the reflector the back radiation can
be changed only by several decibels in one direction or the other.
The shape of the reflector boundary has an effect independent of
the distribution of radiation at the reflector. The variation
of the phase along the boundary can only decrease the observed
field in the shadow zone by not more than half an order of
magnitude. If the primary field at the reflector boundary is
decreased to zero, it will only decrease the field in the shadow
zone by an order of magnitude, and the near field of the primary
radiator becomes decisive. This prevents further reduction of
the shadow field by establishment of a zero of radiation from the
primary radiator in the direction of the reflector boundary.

ABSTRACT: By an 'electromagnetic earth' is meant one in which both
the permeability and permittivity are other than unity.
It is shown that, other conditions being equal, for an
increase -in permeability the field -from a source of
normally.-.polarised waves is increased while the field from
a source of tangentially-polarised waves is reduced.
Ferrite is cited as a suitable electromagnetic material
and it is suggested that it could be usefully employed in
waveguide systems. Dipole sources are assumed and the
results are presented in a series of graphs. Figure 1 is
a plot of -reflection coefficient while Figures 2 and 3 are,
in effect, polar diagrams,, Figures 4, 5 and 6 show how

to vertical. There are 6 figures.

ABSTRACT: The question as to the propagation of radio waves radiated frm
a dipole located in a certain height h above the flat homogeneou.3
earth (h > 0 - raised dipole) or on its surface (h = 0 - lowered
dipole) was in-vestigatei by a number of authors and at present
there exists quite a nl;mber of fonaulae for the calculation of
special cases. CoWlete system of general calculation formulae
derived by the author for the voltages of eleabric and magnetic
fields in the air, which, are fo mei by dipoles of -various kindee
under the conditions mentioned, are given in tht:ir final form.
On the basis of these formulae it is possibl,5 'by mean3 of inte-

of finite length. Here the formulae for the fieldo of lowered
electric dipoles are given. The formulae obtained agree with the
known special formulae. Vertical arA horizontal dipoles are in-
vestigatea. Investigation of derived (21) - (23) ~~d other
for:milae shows that in the case of complex relative magnetic
permeability I the charaoter of the decrease of the
e r
normally polarized field may change within the same limits as in
the case of parallel polarization. It follows hereefrom that in
the case of propagation over a domain with iron-ore occurrence
on the surface, it might be of aavantage to apply normal polar-
ization, i.e. to use a normal horizontal dipole or a hcrizontal
fxww. There are 6 references, 3 of which are Soviet.
