Does anyone know the multi track quantity of Chinese radar on J-20 or J-10?
This quora answer claims that Chinese radar is weaker than old F-16 radar

, he doesn't claim that Chinese radar are weaker than old F-16 radar. He claims that the two weakest, smallest, least powerful, export AESA radars that China itself doesn't use in PLAAF fighters, are weaker (according to publicly available information) than the latest and greatest F-16V's new AESA radar.
From the Quora answer

This is roughly comparable to a decade old F-16’s Mechanical radar (APG-68v9) developed as a low-cost upgrade solely for the export market, and that too had better SAR resolution (0.6 meter / 2 feet). For Western phased arrays, you’ve 20 year old Rafale’s RBE2 (PESA) radar with better performance (tracked 40 targets) and that’s with very similar size as JF-17’s radar (Rafale has one of the smallest radome of modern Fighters).

His answer (just glancing through it) seems reasonable.

First of all, no comments were really made about J-20 or J-10C (PLAAF's) radars. He used public information for the two smaller export AESA's designed for JF-17 block 3, a much less capable radar than J-10C's in service with PLAAF. To say nothing of the J-20's which would be more capable than J-10C's radar.

He also talks about F-16V (block 70). Not any "old" F-16. This is literally the latest and most modern F-16 version with a very modern AESA radar.

So no, he doesn't claim that Chinese radar are weaker than old F-16 radar. He claims that the two weakest, smallest, least powerful, export AESA radars that China itself doesn't use in PLAAF fighters, are weaker (according to publicly available information) than the latest and greatest F-16V's new AESA radar.

None of this would be surprising. The F-16 has a larger radome than the JF-17. The F-16 has a much more powerful engine than the JF-17. It has more room for auxiliary power units and probably other advantages over JF-17.

Basically the answer compares the latest JF-17's radars (options from 2018) to the latest F-16V which wasn't even in service anywhere in 2018.
Don't want to nitpick but

1. JF-17 actually has a bigger radome than F-16

2. KLJ-7A is in fact, newer than APG-83

I'm really curious about this one. This looks like something they will field internally. Very large powerful antenna and mobile. If it can detect object in the space, then it could presumably be used to track ballistic missiles. Also at the band it is operating at, it can detect stealth aircraft from very far out.
