A 1--lothod of Estimating the Diffusion Coefficient in the Meteor Zone
N2 is a similar quantity. If S is known, & can be
dotartnined from:
D -x x2 In Ni - 1n N2 (5)
16rt2(S - 1), 'C~ - '- i
Nowl S can be found from the duration distribution of
the stable echoes (the author - Ref 3) and is expressed
by Eq (4). Eq (3) is not very accurate but it appears
to be adequate for most practical purposes. Figures 1
and 2 show the duration distribution of the meteoric
reflections measured on January 9, 1957, in Tomsic, at the
wavelength of 10 in. From the function N(r) , it was
found that S = 2.06 Froin this, it was found that
D = 2. 8 in2/sec, which corresponds to the height h = 90 kin

Atmosphere
PERIODICAL: Izvestiya Akademii nauk SSSR, Seriya geofizicheskaya,
1959, Nr 12, pp 1891 - 1894 (USSR)
ABSTRACT: The method was based on the height 01 of meteors
determined by radar, as degeribed by T.R. Kaiser (Ref 1).
The theoretical fundamentals of the method are given by
Eqs (1) and (2). The height of the atmosphere H was
determined from Eqs (3) and (5), where v 1 arid v2 are
the velocities of tvo meteors. -Figure 1 illustrates the
relationship between h m and v as given by Evans
(Ref 2). As an example, the height of the atmosphere was
calculated from the above equations as Fir,- 6.9 1ar. (Eq 3)
and F16t 6 km (Eq 5). There are I figure and 5 references,
2 of which are Soviet and 3 English.

ABSTRACTs During the radio-echo observations of meteors carried out at
Tomsk on August 11 - 12, 1957 there were registered two maxima
in the number of radio-echoes t a night maximum on 1h - 2h and
a day maximum on 11h 12h . An instrument with A 10 m was
used, impulse power 100 KW, duration of impulse 5 /4 Boor
impulse number - 600 Imp/sec. It is stated that the two maxima
can be reduced to the Perseid stream.

ABSTRACT: If 0 denotes the probability of the ionization and v denotes the
velocity of the meteor, then usually it is put av n .Under
numerous simplifying assumptions (only normal reflection of the
radio wavers from the delebr trail; negligence of the curvature
of the earth and the resonance effect of the plasma et 'c.) the
author obtains 0.75I aec) and differ slightly in the region of
short durations. 2) In the distribution of amplitudes, three groups of reflections
are distinguished - stable, intermediate, and unstable. The distribution of
intermediate radio edioes is similar to that of stable reflections. 3) Distribution
of intervals between appearances of meteor reflections has an exponential character-

ABSTRACT: Linear electron denaity a of ionized meteor trails was determined from 11
radar observaitions of intermediate-type trails at X - 9.59 m. The observations'
were conducted by Kiev State University in 1903. The method is based on the
dependence of intermediate-type radio echoes on.a. The distribution of a waa

ABSTRACT: The author compares data given in a previous paper on the
persistence of meteoric echo signals (D. W. R. McKinley, Canad. J.
Phys, # 1954# 32# 450) with the results of observations W the ten-meter
wavelength in Tomsk in the IGY-IGC-59 period. The parameters of the
instruments used'in making the observations are given. A formula is
given for the duty factor together with a graph showing the diurnal var-
iatiba- ih the duty factor averaged over the IGY-IGC-59 period. These
data ohow that-the duty factor varies from about 0.58 to OoI7 during
the course of the day* The total duration of the reflections is ex-
tremely short, making up about 4% of the observation time. The formula
propoged by McKinley gives a duty factor of 0#176 for theten-meter wave-

ABSTRACT: The results of radar observations conducted on 29 October
1964 during a period in which intensive meteor streams were absent
were used to construct statistical characteristics of the distribution
of meteor radio echoes with respect to amplitude and duration. The
radar system used had the following basic parameters: X - 8.7 m; pulse
power, 10 kw; pulse period, 10 psec; pulse repetition rate, 500 pulse/

Yagi antennas were located at height h - A/2 above the ground. The

ABSTRACT! The results of meteor-observations by radaroin the Geminide
shower were used to determine the character of distribution of meteoritic
bodies with respect to their kinetic energies. The observations were
conducted, in 1963 at the Tripol'ye Station of Kiev State University*
The radar system had the following parameteraj pulse power, 20 kv;
pulae duration, 10 usec; and pulse repetition rate, 500 pulse/sec. The
::four-element receiving and transmitting Yagi antennas were located at
.hei8ht h - 1/2 above the ground. Only those meteors whose velocity and
:linear electron density could be determined were considered. The dLs-
tribution of meteoric bodies with respect to kinetic energies was found
