MOON CONE RADARS,
CHINA
MOON CONE radars, apparently another
physical modification of the obsolete American
SCR-270 radar of World War II vintage, have
been observed on photography at a number of
locations in China (Figure 1). This report dis-
cusses the MOON CONE radar, presents de-
tailed sketches and dimensions of it and other
Communist Chinese SCR-270-type radars, and
includes photographs of seven sites at which
the MOON CONE has been observed.

CONE radar suggests it to be a further modi-
fication of the obsolete American SCR-270. A
number of SCR-270-type radars are known to
have been obtained by Communist China from
the USSR, primarily the SCR-270DA (Figure 3)
and the SCR-270DB (Figure 4). Although now
considered obsolete by Western standards, vari-
ous copies and modifications of the basic SCR-
VN
270 design have been made by the Chinese
Communists and have been observed in cur-
rent use in their radar systems. Figure 5, for
example, illustrates a Communist Chinese modi-
fication of the 4-element SCR-270DB, in which
the only physical difference appears to be the
addition of 2 elements.
Generally speaking, only low-level or
ground photography is of sufficient scale to
enable precise identification because the lack
of visual detail on high-level photography tends
to place all the various models in a general
SCR-270-type category. However, it has been
possible to observe and identify MOON CONE
radars on photography at seven locations in
China:
Lin-fen, 36-03N 111-30E (Figure 6)
Hsi-an (Sian), 34-40N 108-58E (Figure 7)
Shen-yang (Mukden), 41-47N 123-17E (Figure 8)
Li-shui, 28-28N 119-57E (Figure 9)
Cheng-tu, 30-46N 104-04E (Figure 10)
Lo-thing, 28-04N 120-58E (Figure 11)
Chang-sha, 28-05N 112-57E (Figure 12)

Of the seven radars observed at Cheng-tu,
only one can be positively identified as a MOON
CONE, but such measurements as are obtainable
suggest that the, other six are probably of the
same type. At the Chang-sha location, precise
measurements were precluded by photographic
quality and rectification difficulties even though
the radar was observed on ground photography.
However, this radar and the others shown in
Figures 6 through 12 seem identical in overall
proportion and appearance to the MOON CONE
radar definitely identified on low-level aerial
photography at Lo-ching.
