Russian sources, Chinese sources...we have a reliability problem here. You're going to need to do more than site sources on this forum for any verification.

I believe J-10B use AESA, not PESA

Thanks guys, I really appreciate your quick response.
Bltizo, i saw both the images @
along with these two Radar Images, I hope some senior member here can make some type of connection between the Radars and their? details.

check J-11, I already upload it 2 week ago.
the russian claim that clone copy of SU-30mkk already been produce,as J-16.

So where is this mythical J-16 which looks identical to the Su-30MKK?
yeah...the keyword there is 'appear' to be.
This the Sukhoi T-50 NO50 - (With the cover). Looks identical to the Su-35S N035 - . But when the NO50 cover is removed -
Here's the AN/APG-81 - compare to RBE-2 AESA - , compare to Etla EL/M-2052 - .
So how did you come to a conclusion simply by looking at that picture?
How on earth are IFF modules the same size as the RADAR module? Aren't the IFF L-band and not X-band like the RADAR? Seen the size of the Nebo SVU/M AESA?
Please enlighten me....

You won't see the antenna elements as being exposed and protruding since they're covered by a protective layer of translucent material.
regarding the IFF dipoles issue, it might be the achiles heel of the AESA assumption after all
they are just dipoles as opposed to the T/R modules radiating elements, so they need their own receiver, which is a counterintuitive to an AESA design which does not need separate transmit and receive module
it is also possible that these L-band IFF dipoles are intended for ECM/ECCM operations, leaving the X-band elements to search, track and fire control
another problem if we are to assume that this radar is a full-bred AESA, that this layout is used primarily by early Russian PESAs, later PESAs discard the use of such dipoles
Russian PESAs from the earlier to the later:
Russian NIIP AESA and construction :
F-35 AN/APG-81 AESA and T/R module:
so although the T/R modules themselves are contemporary, the design layout is probably legacy
the reason why PLAAF choose to employ this layout i believe is simply to keep cost per fighter down
assuming the T/R modules are GaAs based, with around 1600 modules count, we arrive at 8-10k watts peak power, which is pretty good for a J-10B sized fighter
