J-7G is an improved variant of the J-7E by CAC, first flew in 2002. Equipped with a new KLJ-6E PD radar,
which is reported to be SY-80 radar, meaning Celestial Eagle in Chinese.
This radar a Chinese development of the Italian Pointer-2500 ranging radar used for the Q-5M,
and the Italian radar itself was a development of Pointer radar, the Italian copy of Israeli Elta EL/M-2001.
In comparison to the Italian Grifo series radar on Pakistani F-7s, the SY-80 weighs more at 60 kg, and the range is also shorter,
at 30 km. However, the radar does have a feat that the Italian radars do not have:
it is fully compatible with helmet-mounted sights(HMS) so that both the radar and HMS can be worked together to control PL-8/9 air-to-air missiles.
One 30 mm gun was removed, and a more powerful engine installed.
