ABSTRACTo The radioastronomy antennae are needed for the determination of the
data on the distribution of "radio brightness" among the cosmic
sources and for the study of point sources, the diagrams of
directivity of which are accurate up to angular minutes. Measuring
these diagrams according to cosmic sources is difficult.
Diagrams of the antennae with an aperture of D - 3,5-103 X can be
recorded in the Fresnel zone and can be coupared with the cor-
responding computed diagrams. In this case, however, the distances R
of the order of some kilometers must be selected for the purpose
of making the diagram sensitive to small phase modifications. This
difficulty, however, can be avoided by means of deliberately
creating a phase difference at the aperture of the antenn which com-
pensates the distance caused by the finite distance in the measuring
zone. This phase difference at the aperture of the antenna can be

the focus, by deformation of the mirror (if the antenna consists
of individual movable parts), etc.
The present work examines the problem of the meaouring the direc-
tivity diagram by taking the radiator out of the focus. A diagram
shows the course of the rays in parabolics. Next, a formula for the
phase difference at the aperture of the parabola is given. The di-
rectivity diagram obtained by means of these deliberations corre-
sponds to a remote zone. Expressions for those distances R are
also given in which the diagram can be measured in the case of
shifting of the radiator (out of focus).
This method for the measuring ofiLdirectivity diagram was verified
experimentally by means of a parabolic mirror. The diagrams
measured in near and remote zones agree well with each other.
The author intends to measure the directivity diagram of an
antenna for centimoter waves with an aperturo of about 100 m.
This method is apparently suited for measuring the characteristics
of antennae with small directivity diagrams and for measuring
their amplification coefficients in the case of weak influence

ABSTRACT: The author gives a detailed description of the method proposed earlier
(RZhFiz, 1957, Nr 11, 28739)~,for measuring the directional diagrams of
highly-directional antennae~~fn the Fresnel region. It is shown that
under these same conditions the amplificat-ion factor of the antenna can
be measured at short distances. Using the radiotelescope of the Main
Astronomical Observatory, which has an aperture length of ,- 100 m, the
method was verified experimentally on 3 ojid 10 am wavel,~ngths and at
distance of 4.2 km from the transmitter.

ABSTRACT: A description is given of an experimental test of a
proposed method of measuring the parameters of a narrow-
beam antenna within tho Fresnel zono. Mleasured
patterns and gain factors are given.for systems with
apertures of about 1000 1& and 2000 Io The effects of
some errors in the surfaces are examined. Antenna
systems of large aperture have become common in radio
astronomy. These systems have main lobes only a
fraction of a. degree wide. There are serious difficul-
ties in adjusting such systems, because the field
patterns involve distances of hundreds of kilometres.
It is not possible to measure the patterns at such large
distances. The author has proposed (Ref 1) a method
of measuring thextterns at relatively short distances
(a few kilometre , i.e. within the Fresnel zone. The
out-of-focus effects caused by the finite distance are
Card 115 compensated by shifting the emitter away from the focus.

'Experience with Adjusting a Large Radio Telescope
To make measurements at a-distance R the emitter has to
be moved from the focus by a distance b given by
b = f2/R (1)
or e 2/1+f2l,
b = (fVR) 11 + a (2)
where f is the focal length and 2a is the width of the
paraboloid at the focus. This method has been used with
the telescope at the . Main ' Astronomical Observatory
at Pulkovo, which was designed by Khaykin and
Ka~danovskiy; the axis was set horizontal for the
purpose, (Ref 2). The reflector is 'then a paraboloidal
cylinder of height 3 m. The bottom edge of this
cylinder is 1.5 m above the ground. The reflector is
made up of separate adjustable strips, and so the
horizontal width of the cylinder can be varied from a
few metres up to l,-,O m. The straight antenna works at
3 am and 10 cm. This rod is 1.5 m iltbove ground, with
its contro placed symmetrically relal;lve 6 the cylinder.
At 3 am the author used 2a = 50 m, and at 10 am
Card 2/5 2a 100 m. In both cases f = 46 oni. = At 3 am
(2a 50 m) the pattern is formed at R 160 km, and at

10 cm (2a = 100 m) at R = 200 km. In both cases
measurements were made at R = 4.2 Ian. The antenna did
not work optimally with 2a 50 m (0.4 Pmax at the edges?
instead of 0.1 Pmax at 2a 100 m). Fig 1 shows
the pattern found with 4a. 50 m. with the antenna at the
focus, or displaced from the focus. Fig 1, Curve 3,
shows the pattern given by a point source (a spot on the
sun). Fig 2 gives the patterns found at R = 4.2 and
from a sunspot for 2a = 100 m. Fig 1, Curve 2, shows
that, at R = 1+12 km and with the antenna at the focus
(b = 0)9 the diagram is badly distorted relative to the
real one (curve 2); the real diagram (curre 3) and the
one recorded at the close distance with the antenna
displaced (curve 1) agree quite well, The antenna with
a source placed at R = f2/b Is equivalent to a properly
focussed one within the wave zone. Hence one can
measure the gain of the antenna and can find the proper
Position for it, and can determine the effects of errors

Fig 4 gives the pattern with the reflector di3torted to
give a periodic phase shift with a period of 3m, where
4-81 is the deviation from a true paraboloid. Fig 3
shows that &-e = V)+ results in no emission at all in the
principal direction. Fig 1+ shows that the periodic
error causes side lobes, whose angular distances from the
main lobe are determined by the period of the error.
The gain of the system was measured relative to the
antenna without the reflectorg or relative to the antenna
with the standard horn. The value was 52 db for
2a = 50 m and X = 3 cm, which corresponds to a coefficient
of use of the surface of 0.12. This low value results
from poor illumination of the mirrors and from errors in
the antenna. (A new antenna has since been made, which has
less loss and gives better illumination- the corres-
ponding coefficient is 0.25 (gain 56 dbi.) The results
Card 4/5 show that the patterns can be recorded and the system
adjusted by making measurements at short distances.
