According to Chengdu Aircraft Industry Corporation
officials the J-10 uses a multi-mode fire-control radar designed in China. The radar has a mechanically scanned planar array
antenna and is capable of tracking 10 targets. Of the 10 targets tracked, 2 can be engaged simultaneously with semi-active radar homing
missiles or 4 can be engaged with active radar homing
The radar is believed to be designed by the Nanjing Research Institute of Electronic Technology (NRIET), designated KLJ-10 and a smaller variant is claimed to be installed on the JF-17
Believed to be based on technologies from Russia, Israel or a combination of both, the radar should be comparable to Western fighter radar designs of the 1990s. It may also be replaced by more advanced radars of other origin on export versions of the J-10. The Italian FIAR (now SELEX Galileo
) Grifo 2000/16, has been offered to the Pakistan Air Force
for installation on the J-10, should the PAF induct the aircraft.
