JY-11 LOW-ALTITUDE 3D AIR SURVEILLANCE RADAR

(Last updated 10 September 2006)

The JY-11 is a full-solid state, frequency-scan low-/medium-altitude 3D air surveillance radar developed by China Electronics Technology Group Corporation (CETC) 38th Institute of Hebei, Anhui Province. The S-band radar system is designed to detect and track targets at low-altitude and provide target information for air defence weapon systems. It can be used as a stand-along system, or as a part of a multi-sensor air defence weapon network. The whole system comprises three transportable units with the capability of fast automatic assembling and dissembling.

The JY-11 achieves azimuth scanning by mechanical rotation of its radar antenna, and vertical scanning by electronic frequency phase scanning. The radar antenna creates multiple scanning beams with different operating frequencies and elevation angles in an instantaneous vertical plane. The radar also features low pulse peak power and ultra low SL level, thus reducing the possibility of being detected by enemy radar warning receivers and anti-radiation weapon systems.
