The JL-10A airborne radar is a highly digitized pulse-Doppler radar with slotted planar array developed for the People's Liberation Army Air Force (PLAAF) as a replacement for the older Type 232H radar currently employed by the Chinese air force. The radar is built to MIL-STD-1553 standard so it is compatible with western electronics and weaponry. Originally, the radar is capable of simultaneously tracking 10 targets (later to be upgraded to 15) and engaging 2 (later to be upgraded to 6) of the 10 tracked when using semi-active radar homing air-to-air missiles, or 4 of the 10 tracked when using active radar homing air-to-air missiles.
