ABSTRAM The authors consider, on the geometrical optics
approximation (Ref 8), amplitude and phase fluctuations
of radio waves propagated in a turbulent medium in the
presence of a plane separation boundary. In this case,
the resultant field at the detector e is given by the
sum of the direct wave and the wave reflected from the
separation boundary (Figure 1). The two fields are given
by Eq (1) in which R and 0 are the modulus and the
phase of the Fresnel reflection coefficient, respectively.
The amplitudes and phases of the signals can be written
in the form given by Eq (2), where the quantities with
subscript 11011 are inean values and AE i and Ayi are
the fluctuation components of the corresponding quantities.

The Effect of the Separation Boundary on the Fluctuations of Radio

in the form given by Eq (5), where the symbols are
defined by Sqs (3) and (4). In the case of small
fluctuations, one has the approximate relations given
by Eqs (6) and (7) and the phase of the resultant signal
is given by Eqs (8) and (9). Assuming that the medium
is isotropic, and using Eq (9a), one obtains Eq (10),
where R E and R If are the correlation coefficients for
amplitude and phase fluctuations. Eq (10) was obtained
by neglecting the small quantities given by Eq (11).
When V 1. = 2T(h , E and 4) are given by Eq (12). In
order to carry out numerical calculations, it is assumed,
as a first approximation, that the amplitude and phase
fluctuations of the separate components e I and e 2 of
the resultant field (Eq 9a) are the same as in the absence
f the boundary. In that case one obtains Eq (14), where
is the scale of izmgularities . Using Eqs (15) and
(141), Eq (10) may be written in the form given by Eq ( 6

It is clear froin Eq (16) that, under the above asswnpti-is.
the amplitude and phase fluctuations in the resultant
signal are equal in the distant zone. However, the
dependence of the intensity of fluctuations on the -kvaire-
length, the parat-tietGr L, and the distance rI (Figure 1)
may be quite different from that in an infinite medium.
A comparison of this theory with experiment shows good
agreement and hence it is clear that in practice it is
necessary to take into account the effect of the boundary
on the fluctuations. The above solution was obtained for
the plane problem. It would be desirable to obtain a
solution for a spherical Earth.

ABSTRACT: The propagation of waves in a non-homogeneous turbulent
medium m = n(r, t) is accompanied by amplitude and
phase fluctuations whose statistical properties are chara-
cterised both by their intensity aad correlation at various
points in space. Most of the papers in the literature
(Refs 1-7) have been concerned with the determination of
the intensity of the fluctuations and their Gorrelation
along special directions and along the direction of propa--
gation. The present paper is concerned with the case of
an arbitrary disposition of the points under consideration
A and B (Figure 1), relative to the source of
radiation 0 . Formulae are derived for the coefficients
of longitudinal and transverse sorrelation of phase and
amplitude fluctuations. It is shown that by measuring the,

ABSTRACT: The results of an experimental measurement of the

verti,~~ally polarized radio wayesSover the sea surface are
reported. The frequency employed was 3 000 Me/s and the
experiments were carried out under various nre-teorologi-cal
conditions during July=,September and October-pe~_-ember
over a sea route having a length of 33 km. The differential
method of measurement was,.empXoyed, in which the fluctua-
t1lorns of the phase differences of the signals recalved by
dtversity antennae were-employed to determine the intensity
and the decorrelation of the phase fluctuations at Var3.OUS
points of the wave front. In order to reduce the effect
of the boundary refraction, the receiving systems were
situated at distances of 2, 5, 10, 30 and 100 m from the

first (the standard) antenna. Altogether six antennae
were employed. The antennae were situated about 4 gi above
the sea surface. The error in the measurement 8f the
phase-d.ifference fluctuations was less than :t I ,even
if the amplitude of the received signals varied as much
as 60 db. The measurement showed that as a rule the
deviations 9 of the phase differences with respect to
the average value obey the normal law for all the trans-
mitter heights h 1 and the distances between the antennae.
The results of the measurements are indicated in Figures I
to 11. Figure I gives the overall distribution of the
phase-difference fluctuation for various distances between
the receiving antennae. Figure 2 shows the normalized
energy spectrum of the "slow" phase fluctuations for
various distances between the antennae. Figure 3 shows

ABSTRACT: Earlier papers dealing with this subject mainly take the
amplitude fluctuations of radio signals into account. The
phase fluctuations were investigated only in the zone of
direct visibility (mainly over the mainland). The present
paper deals with the least investigated problem, namely the
experimental investigation of phase-front fluctuations over
the sea. Ueasurements were carried out on the wave -,%-= 10 cm
in the case of vertical polarization during the period of from
July to September and October to December along a line of
33 km length leading exclusively over the sea within the
boundaries of the "illuminated zone". the "half-shade" and
Card 1/4 "shade". In these investigRtions the differential method was
-The Fluctuations of the Phase Fronts in the SOV/20-125-5-18/61

used, which (by measurement of the pulsation of the phase
difference of the electromotive force in some reception
antennas) make determination of the amount and the degree of
decorrelation of wave front, fluctuations in distributedly
arranged measuring points. The arrangement of 6 measuring
antennas along a straight line for this purpose is described.
In this way it was possible to measure phase fluctuations
within the frequency range of from 0.01 to 100 cycles. Besides,
provision was made for the possibility of filtering and sepamte
0.3 cycles) and high-
indication of low-frequency (e,
frequency (-,;, 0.3 cycles) (i.e. of the so-called "slow" and
"fast") fluctuations. According to the results obtained by
these measurements the fluctuations of phase differences were,
with rare exceptions, distributed in accordance with the
normalAaw. However, the fluctuations observed can be
coordinated to the steady random processes only with certain
reservations, for various cases of phase difference
fluctuations of signals were detected. The dependence of
fluctuation intensity on the intervals between the measuring
Card 2/4 points remained qualitatively equal in the case of all
The .. Fluctuations of the Phase Fronts in the SOV/20-125-5-18/61
Propagation of Decimeter-radiowaves Over the Surface of the Sea
experiments. The character of the height-dependence of
intensity was considerably more manifold, and therefore it
also served as a basis for the classification of experiments.
All measurements may be subdivided into 4 main groups:
1) Quasisteady standard type of phase-fluctuations. Most
experiments belong to this group which is characterized by
a monotonous reduction of fluctuation intensity with an
increasing height of the transmitter. Such a dependence is
found with propagation within a local isotropic troposphere
over a plane separating surface. These measurements have a
high degree of steadiness and good reproducibility of the
intensity and spectral composition of fluctuations. 2) The
nonsteady standard type of fluctuations is characterized by
a considerable non-steadiness of the fluctuations. 3) The
anomalous type of phase-fluctuations: in measurements of this
group the heig~~-dependence differs considerably from that
of the standard type. 4) The "flaring up" of fluctuations.
This state usually did not last longer than a few dozen
minutes, after which the usual state of the fluctuations was

From Eq. (1), it follows that in order to match the balancing
junction with the feeder over a wide frequency band, it is
necessary to reduce the parameter ~ . However, this does not
permit the elimination of the reactive components. It is
possible to compensate this reactance by means of an additional
quarter-wave open-ended line section or by short-circuited
quarter-wave loops of coaxial lines having a comparatively high
wave impedance; these devices are illustrated in Figs. 2.
This compensation does not affect the resistive component of

TITLE: Automatic Measuring Line for Short Radio Waves
PERIODICAL: Pribory i tekhnika eksperimenta, 1961, NG. 1,
pp. 112 - 116
TEXT: The measuring lines (including automatic ones) are
widely used for various measurements at ultrahigh frequencies
(Refs. 19 2) but at metre waves it is necessary to employ
bridge methods of measurement, These methods have a number
of disadvantages and, consequently, an attempt has been made
to devise an automatic measuring system based on a measuring
line. The system described can be used at frequencies from
10 - 40 Mc/s. The system employs a multiprobe line from
which the signals are taken by means of a switching device.
A standard coaxial cable PK-1 (RK-1), having a length
t = 0.35 kmax (where ~ - 10 m) is used as the line; this
is helically wound on a drum having a diameter of 300 mm.
A number of probes (30 in all) are situated at equal distances
along tho line, the probes being coupled rather weakly with
Card 1/3

Automatic Measuring Line .... E192/E382
the line. The signals from the probes are detected by
suitable detector stages. The coupling between the probes
and the line is adjusted mechanically as well as electrically,
so that all the probes have the same sensitivity. The standing
wave pattern is observed by successive switching of the out-
puts of the detector stages to the input of a measuring ampli-
fier. The signals from the amplifier are applied to an
oscillograph indicator. Since the coupling between the wave
inside the cable and the probes has to be very low,'~the
amplifiers must have a gain of about 120 db. The switching in
the instrument is performed by a multicontact frictionless
mechanical switches; the contact pairs close in succession.
In order to reduce the interference produced by the switches
the wave in the cable was amplitude-modulated. The optimum
modulation frequency was dependent on the construction of the
switching system. This frequency was 500 - 1 000 c-P-s-, the
switching frequency being 3 c.p.-g. Additional reduction in
the interference via the switching device was achieved by
providing the amplifiar with a low input resistance

(about 7-5 kS,). Physically, the instrument consists of
three unitst a high-frequency variable generator; a multiprobe
line and an amplifier plus indicator with stabilised supply
sources. The system permits a comparatively rapid measurement
of the standing-wave ratios and phase. The instrument can also
be used for the measurements of impedances and progressive
waves, which is of importance in the adjustment of antenna
systems and feeder lines. There are 4 figures and 2 Soviet
references ( one of which is translated from English).

TEXT-~ The instrument described was designed and built at
the IRE AN UkrSSR (Institute of Radio-electronics of the AS
UkrSSR) and has an operating bandwidth ranging from 10-40 Me/s.
Constructioxally., it is in the form of two separate units,
the radial frequency unit and a mechanical system. The mechanical
system comprises a multiprobe line, a high-frequency capacitative
switch. a capacitative current probe-and -collector and a
synchronous drive motor operating at 1 500 r.,p.m, The line of
the system is in the form of a coaxial cable, type PV-6 (RK-6),
having an impedance of 52.-TI. and a length df 10 m; it is wound
helically on a toroid,, The electrical unit of the device
consists of four circuits,~ a signal generator; an amplifier;
a synchronous time-base and an indicator (output) circuit. The
design principle of the instrument is illustrated in Fig. 1~

The signals from the HF generator I , which has a wide operating
range, are applied to the input of the long-line 2 , which is
terminated by the measured load, Weakly-coupled., screened
probes are inserted into the line at equal intervals. The HF
oscillations pj-cked-up by the probes via the RF capacitative
switch 3 , the pick-up and the cylindrical co.llector 4 14-
(which is driven by the synchronous electric motor) are applied
successively to the input of the measuring amplifier 5 . The
HF signal of the generator is modulated by a low-frequency F M
and the amplifier 7 , which is terminated by a noaresonant
detector, is tuned to this frequency~ During uniform rotation
of the switch pulse signals are produced at the output of the
amplifier and these are applied to the vertical plates aX the
cathode-ray indicator tube 6 . Simultaneously, a trigger
time-base waveform is applied to the horizontal plates of the
tube from the amplifier 7 ; the time-base is triggered by thE:
signal received from the first segment of the sw2.tch, which is
produced by a special auxiliary generator 8 , whose operating

frequency lies outside the operating range of the instrument-
In this way, a screen of the indicator tube shows the distri-
bution of the I-IF voltage along the line, the picture being in
the form of a oeries of pulses. The en%relope of these pulses
determines the phase a 'nd modulus of the reflection coefficient
of the measured load. If the signals appearing at the output
of the 'iF si-,itch are detected directly, the instrument can be
used to measure the power standing-w-ave ratio. On the other
hand, if an auxiliary non-modulated RF signal of a large
amplitude is applied to the input detector, the voltaZe
standing-wave ratio is measured. The instrument has been
testedovcr a long period of time and it was found extremely
us,~ful in the adjustment of various types of antenna systems,
matching devices, matching of feeders, input circuits of the
receivers, filters, etc. There are 2 figures and 2 references:

TEXT4 This is a rt of an experimental investigation on 10 cm
vertically poiariVowaves transmitted over a fixed sea path of
length 33 km, using two receiving antennas separated by a distance
d ranging from 2 to 100 m transverse to the path. An object of the
investiration is to obtain more detailed data than presented previ-
ous -!v. The spectrum of fluctuations in the range from 0.005 - 0.01
to -1 -200 c/s is studied. The heights of the receiving antennas
(h) w----e about 4 m; the height of the transmitting antenna (ho) was
given different values of 35, 18 and 9 m. The period of the investi-
gation covered summer, autumn and winter, thus including varied

meteorological conditions. The records obtained were analyzed by
numerical methods; one method involved "discretization" of contin-
uous records and recovery of Fourier components. Another "continu-
ous" method made us of a mechanical correlator. Narrow-band filters
with band width 1/T were used for the analysis, T being the Waly-
sis interval. The spectral distribution observed for the different
values of ho and for d = 2 and 10 m are qualitatively similar. The
data obtained indicate a tendency to sharp reduction of spectral
density at higher frequencies, evidenced most clearly at higher
values of d and hoo peak density occuring between 0.1 and 1 c/s.
Analysis of a large number of measurements confirmed the essentie-I
non-stationariness. While the general intensity of Wluctuations vas

sity of fluctuations together with a spectral re-distribution -,Q-
nerally towards lower frequencies. Fluctuation intensity varies as
T-1, as for "white" noise. The variations of mean spectral density

increasing in some cases to � 10 db, and over; spectral density de-
creases rapidly as frequency increases, the relatior following an
inverse 1.5 law for d = 2 and an inverse 2.5 law for d = 10 m. The
results are in good agreement with those given for fluctuations of
absolute phase as long as d is sufficiently large compared with 1,
the characteristic correlation dimension - (2 - 3 m). Where direct
analysis cannot be applied, a statistical method is used. The in-
fluence of meteorological conditions was investigated by making
measurements of pressure, temperature, wind and humidity at four
points along the path; no clear connection could be shown between
the spectra of fluctuations and the meteorological conditions. There

conditions. An experimental-theoretical comparison proves the considerabl~-
influence exerted by taking the boundary into account: It leads to a
quicker increase of fluctuations with growing distance, to a change in the
frequency dependence, to the occurrence of fluctuation flashes, to a quick
increase of the fluctuation intensity in the minima of the mean field, etc.
The problems to be theoretically solved in future consist in taking the
curvature of the boundary, the anisotropy, and the instability with time
of the medium into account. B. A. Vvedenskiy is mentioned. There are

TEXT: According to the above hypothesis, first put forward
by V.A. Krasillnikov (Ref. 1 - Izv.. AIN SSSR, ser. geogr. i
geofiz., 13, 33, 1949), the transport of irregularities in the
medium by wind has a primary effect on the cliange in radiowave
fluctuations with time. It has been shown that the transport
effect can be described with the aid of spatial correlation
and autocorrelation functions. It is a-ssumed in such calcu-
lations that the prop.grties of the medium remain unaltered
during the transport process and it is not -always clear whether
the assumption is, in fact, justified. In this connection
the authors investigated the possibility of the direct

determination of the transport effect in the troposphere
and estinated the effect of turbulent motion, diffusion,
thermal conductiv-ity and convection on the fluctuation
characteristics. It is shoim that space-tii-zie correlation
functions of fluctuations can, in most cas,es, be used to
establish the presence of the transport effect among other
processes occurrin.- in the medium and to estimate the effect
of these processes on the time characteristics of fluctuations.
A number of graphs are given to illustrate the application of
the correlation functions to these problems. These calculations
are of interest in the case of radiowaves propagating along
different routes in a nonuniform turbulent medium.
There are 4 figures.

TEXT: This is a continuation of previous work by this author
(Izv.VUZ. Radiofizika, v.5, 1962, 70). The results obtained in
that paper can be used in conjunction with experimen-lal data to
verify the presence of transport of medium irregularities both in
the case of frozen-in turbulence and in the more general case of
unfrozen turbulence. The experimental verification of the
theoretical results was carried out by studying amplitude
fluctuations of vertically polarized radio waves (X = 10 cm) over
sea water along a fixed path of 30 kin. The receiving antennas
were at a distance of 2 to 100 m along a line perpendicular to
the direction of transmission. The experimental procedure was as

1955, 1391) and the present author (Radiotekhnika i clektronika,
n6.7, 1962, 232). The measurements were repeated under various
meteorological conditions (summer and autumn). Analysis of a
large volume of data indicates the presence of a transport effect
in most cases. The transport of frozen-in turbulence was Li
detected in 505 of cases. The effect of other processes
occurring in the medium (in addition to the latter effect) was
detected in 40% of all ca&es. No clear transport effect was
found in about 10510 of all cases. However, there is a considerable
discrepancy between the experimental results and theoretical
predictions. Analysis of the radio data shows that the processes
occurring in the medium are non-stationary and the ergodicity
condition may not hold. There are 8 figures.

TEXT: The correlation between the amplitude and phase fluctuations

shown that the correlation coefficients of the amplitude and phase)

stations, weak and medium bursts could not be observed. On
July 12, 1961, at 10 hours 20 minutes U.T. there was a rapid
increase in ionospheric absorption followed by an almost complete
fading bf all radio signals between lU and 25 Nic/sec.
Immediately after this, the solar radiation flux density rose to
about 10-19 w/m2 cps and the enhanced emission continued until
IC hours 55 minutes. After the termination of the radio burst
the enhanced ionospheric absorption continued for a further four
hours. Since the reception of the radio emission was carried
out in the side lobes of the antenna no details of the phenomena
are reported. On July 18, 1961, at 9 hours 50 minutes U.T., a
region of enhanced radio emission was found to move in from the
hign-frequency side and had a sharply defined low-frequency cut-
off. The rate of drift of the low-frequency cut-off was about
2 ',~,c/scc/sec so that the spectrum was classified as belonging to

chromospheric flares. The onset of the bursts was simultaneous
with the increase in ionospheric absorption of the type reported
by k. Sheridan and G. Trent (Observatory, v.81, 921, 1961, 71).
This phenomenon may be clue to an increase in the ultraviolet
solar radiation. In the steady-state stage, the emission
consisted of a number of separate bursts which drifted at random
at the rate of about 1 Mc/sec/sec towards both low and high
frequencies. The width of each burst lay between 0.5 and
5 Mc/sec,

40 Mc, the fluxes of Cassiopeia-Aj Cygnus-A, Taurus-A, and Virgo-A
were measured in the 12.5--40-Me range., for which no reliable abso-
lute values are known. presently. To improve the accuracy, absolute
measurements were made only for the aost powerful source, Cassiopeia-
A, using seven sets of radio interferometers with half-wave dipole
antennas. The other fluxes were determined relative to this source.
The 'collapse' of the spectrum at high frequencies was noted for all
but Taurus-A. The emission measure and the ratio of the normal com-
ponent of the magnetic field to the number of electrons per cubic
centimeter of the discrete sources calculated from these measurements
are 3.5, 3.5, 5.0 and 700, 700, 120 for Cassiopeia-A, Cygnus-A, and
Virgo-A. It is assumed that the decrease in the spectrum is due
either to absorption in H.1 clouds or by a decrease of the refractive
index in the source. Orig. art. has: 2 figures, 4 formulas, and

ABSTRACT: A receiving antenna intended for radioastronomical inves-~
tigation of discrete sources and cosmic background in the 20-40-mc
range is described. The antenna was designed on the principle that
the electric control of the beam at large scanning angles can be
realized by phasing low-dLrectional discrete elements, whose large

number.insures the required degree of resolution. The antenna arralf
located along the W-E line, consists of 128 half-wave wide-band
cylindrical dipoles arranged in 4 rows, each carrying 32 dipoles.
The cylinders, formed by 18 elements of 8 mm each, are I m in diam--:
etere The distance between array-element centers along and across
the array is 5.5 m. The array elements are suspended 3 m above the
I ground. The signal excited in each element is transmitted to the
output of each row through a matching balancer, three adders, and
three coaxial cables with a total length of 101 m. The toroidal
ferrite transformers used as adders made it possible in the 10- to
60-mc range to achievp a VSWR of 1.05 or better at a rated load
with an efficiency of 95 to 97% or better. The electric control
of the beam, which is accomplished by inserting delay cables be -
tween the adder and the output of each rowp is carried out only in
the N-S planes The radiation pattern and gain of the antenna were
determined by the simultaneous recording of signals from Cassiopea-A'

ABSTRACT, A method of measuring the parameters of a multiple-unit electri-
cally steerable antenna (musa) under operating conditions without Introducing
noticeable distortion into its circuit is considered. A low-loas measuring line is
connected between the output point being measured and the load (radiators), and
the values of loop and node voltages are noted. Then, a calibrated attenuator I
connected in place of the multipole being tested, and the attenuator is adjusted
until the same values of the loop and node voltages are attained. Simple formulas

errors ii-tivolved are theoretically assessed. The method was used in practice to
measure the efficiency of a IZ8-unit electrically ateerable radioastronornic
antenna described by L. L. Bazelyan, et al. (Elektroavyaz, 1964, no. 4). A
5Z-ohm multiprobe automatic measuring line was used. Estimated and measured
efficiency curves are shown for frequencies within 20-40 mc. "In conclusion, the
