The Chinese AWACS has a unique phased array radar (PAR) carried in a round radome. Unlike the U.S. AWACS aircraft, which rotate their rotodomes to
give a 360 degree coverage, the radar antenna of the Chinese AWACS does not rotate. Instead, three PAR antenna modules are placed in a triangular
configuration inside the round radome to provide a 360 degree coverage.
The Chinese-made airborne earning warning radar system could be similar in capability to the IAI Phalcon, but may not be as capable as the latter. The
Phalcon system could track up to 60~100 targets at the same time and guide a dozen fighters in all-weather, day and night operations.
The photos of the KJ-2000 indicate that the aircraft has an aerial refuelling probe in its nose. If the aircraft can be refuelled by the Russian-made
IL-78 Midas tanker, its flight endurance and effectiveness could be further increased.

Looks promising... apparently built with fully indiginous technology after Isreal and Russia backed out
