This report has been prepared in answer torequirement DIA-AP1-
63-89 requesting information concerning the dimensions and con-
figurational characteristics of the surface-to-air missile (SAM) guidance
radar associated with the SA-3 SAM system. In addition to the ground
photography referenced in the requirement, available photography per-
mitted analysis of radar components being assembled at the Moscow/
Fili Airfield radar assembly area resembling those at Ostrov Nargin
and Mys Set-Navolok.

There are overall similarities in certain
components of the guidance radars at Ostrov
Nargin, Mys Set-Navolok, and the Moscow/Fili
Airfield radar assembly area (Table 1). A
total of nine different components are visible
at the three sites. Two of these--a trough and
a cut paraboloid--are present at each site.
Other components visible at Mys Set-Navolok
include a peel with feed, an unidentified object,
a single circular section, and a stacked circular

section. The latter two components are also
visible at Ostrov Nargin, but not at the Moscow/
Fili Airfield radar assembly area.
It cannot be determined whether configura-
tional differences in the guidance radars
are due to the poor quality of the available
photography or to actual differences in design.
The photography is of sufficient quality to de-
termine that the radars are not of the FAN
SONG type.

The SA-3 guidance radar at Ostrov Nargin
(Figures 1-4) consists of five different com-
ponents mounted on a chassis, as illustrated
in Figure 5. The back-to-back circular section
(Figure 5, item I) is attached to the rear of
the chassis by a lattice-type mast and may have
the capability of being raised or lowered. A cut
cylindrical section (item C) is mounted on top of
the chassis and appears to have the capability
to revolve. Two cut paraboloids (item B), one
with a. feed and one without, are located on top
of the chassis over two troughs (item A). One
trough is horizontal and parallel to the front
of the chassis; the other is also horizontal,
but attached to the side of the chassis. At the
base of the chassis, under the latter trough, is
a stacked circular section (item G).

The SAM guidance radar at Mys Set-Navolok
(Figures 6-9) consists of seven different com-
ponents mounted on a heavy lattice mast, as
illustrated in Figure 10. A chassis mounted
on top of the mast holds four of the compo-
nents (Figure 10, items A, B, D, and H). An
unidentified component (item H) with a small
feed is mounted topmost on the chassis. Below
this component is a cut paraboloid (item B)
attached to the chassis just above a trough

(item A), which is horizontal and mounted on the
chassis in a manner similar to that of the side-
mounted trough at Ostrov Nargin. Another
trough (item A) appears to be located on the
other side of the chassis and slanted at a 45-
degree angle to the ground. A peel (item D) is
situated on the far side of the chassis. Halfway
up the mast that holds the chassis are two
lattice-type arms. At the end of one arm is
a single circular section-type component (item
F), and at the end of the other arm is a stacked
circular section-type component (item G). An
independently mounted feed (item E) is at-
tached to the mast above the two lattice-type
arms. This feed may have the capability of being
raised and lowered.
The four different guidance radar com-
ponents at the Moscow/Fili Airfield radar
assembly area are mounted on two different
chassis, which are in the process of being
assembled (Figures 11 and 12). Two troughs
(Figure 5, item A) are visible mounted on one
chassis, and a cut paraboloid (item B) can be
seen mounted on the second chassis. A cut
cylindrical section (item C) is on the ground
between the two chassis. To the right of the
second chassis a canvas-covered peel (item
D) is lying on the ground. The troughs measure
- feet in length, the cut paraboloid-feet
in width and =feet in chord, and the cut
cylindrical sectionEfeet in length.
