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 missiles.

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 light-weight fighter.
[24] 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.
