PROBABLE RADAR CROSS-SECTION TEST SITE, CHINA (S)
INTRODUCTION
1. A probable radar cross-section test site was identified for the first time in China on
imagery of The test site is part of Su-Tsun Probable Electronics Research and
Development (R&D) Facility which is approximately 100 nautical miles (nm) west
of Shanghai in the Nanjing Military Region. Radar cross-section testing is used to evaluate the
apparent size of a target through analysis of its projected size, range, aspect, shape, and material
composition. China may use this facility to test indigenous radars or to evaluate projected enemy
radar images of Chinese aircraft. (S/WN)

DESCRIPTION
2. Su-Tsun Probable Electronics R & D Facility is approximately 2 nm east of Su-Tsun, at 30-
53-10N 110-12-10E. Dispersed over a relatively isolated region approximately 1 nm square, it
consists of an electronics test area, an equipment storage/support area, and a barracks/support
area (Figure 1). (S/WN)
3. The probable radar cross-section test site and an unidentified electronics test site are in
the electronics test area (Figure 2). The probable radar cross-section site (Figure 3) consists of two
lattice towers (one guyed and one self-supporting), a concrete test pad between the towers, and a
smaller rail-mounted lattice tower on the test pad. A cable, suspended between the tops of the
two larger towers, passes directly over the concrete test pad. An LA-17 drone and an unidentified
structure/piece of equipment were on the test pad (Figure 3) on The unidentified
electronics test site consists of a small electronics test pad and two probable calibration buildings.
Four probable auxiliary electronics test pads are on a small hill overlooking the electronics test
area. Numerous storage/support buildings are nearby. (S/WN)
4. The equipment storage/support area, west of the test area, consists of five barracks, one
probable administration building, one equipment storage building, one messhall, and seven
support buildings. (S/WN)
5. The barracks/support area, north of the test area, consists of eight barracks, two
messhalls, and three support buildings. Trenches were observed across the main road from this
area. (S/WN)
6. The Su-Tsun facility was originally identified as a radio communications station when the
guyed tower was first observed in 1964. It was expanded into an electronics test site between April
1971 and July 1972, with the addition of the self-supporting tower and the four test pads on the
hill. By March 1978, a circular concrete test pad had been constructed between the two lattice
towers, an indication that radar cross-section testing had probably begun. By a
cable had been suspended between the tops of the towers, and the test pad area had been
expanded to include a small rail-mounted lattice tower. (S/WN)
Imagery Analyst's Comments
7. Because of its configuration, the possibility also existed that the Su-Tsun facility was
involved in electromagnetic pulse (EMP) research and development. EMP simulator sites in gen-
eral, are typically
equipped with a pulser between the towers to provide electromagnetic transmissions. Further
research subsequently revealed that Su-Tsun Probable Electronics R & D Facility was more similar
in dimension and layout to several Soviet radar cross-section test sites. Comparison of the Su-Tsun
facility to a Soviet radar cross-section test site at Belousovo Probable Electronics Test/Training
Facility2 Figure 5), just south of Moscow, confirmed their similarities-the pad and
suspended cable between the towers and the height and distance of the towers. The lack of a
pulser and the presence of the drone, the rail-mounted tower, two probable calibration build-
ings, and four auxiliary test pads further suggested the function of Su-Tsun as a radar cross-section
testing facility. (S/WN)
