DZ9001 mobile electronic intelligence (ELINT) system (Source: CETC)
The DZ9001 is a mobile electronic intelligence (ELINT) system designed to detect, intercept, analyse, identify and record the enemy radar radiation. By collecting and analysing the signals of enemy radar, their technical parameters and operation modes can be acquired and recorded for both defensive and offensive electronic countermeasures operations such as suppression of air defence (SEAD). The DZ9001 system is composed of 1~8 GHz low-band system, 8~18GHz high-band system and power supply. The high- and low-band systems can operate separately or in together.
The system was developed by Jiangnan Electronic & Communications Research Institute (JECOR, also known as 36 Institute) of Jiangxing, Zhejiang Province. The development began in 1984 and the system entered the PLA service in the late 1980s.
