Too large to be datalink antennas, unless they operate in X-band, perhaps, IMHO. The F-35's MADL operates in K-band and its antenna diameter is about 3 inches.
Unlikely unless maybe in several years. The best guess is Chinese version of MADL. On why there are 2 of them it could be because it works on 100% duty cycle means one antenna will always emit while another receive. Both types are phased arrays, with electronic beamsteering.
Another probable reason is that it works on different frequencies. One hexagon with much clearer "grills" works in lower frequency while the other one with much smaller thus appear to be blurred works in higher frequencies.
You beat(ha ha ) me to it.
Almost certainly this.One alternative theory is that they are boundary air bleed vents or auxillary air intakes related to the intake.

Actually it seems the pic as posted as early J-20 cockpit is really FC-31. The actual J-20 cockpit seen in the photo has a newer HUD and display technology (either one large panel or two next to each other most likely)Looking at those cockpit photos, the panel layout reminds me of the first generation Gripen.
Possibly an interferometry grating for ESM, specifically transmitter geolocation by assessing the phase angle delta between the wave front arriving at the individual holes.[Another probable reason is that it works on different frequencies.

Indeed, poor chap looks like he's going back to the 1970s to watch Jaws 3D at the cinema.Weird visor/HMDS on that pilot´s helmet, especially when compared with western systems...
The helmet itself looks rather oldfashioned and - with that visor - needing the pilot to do headturns to be able to look somewhat sideways when wanting/needing to rely on his eyeballs as sensors.
Any thoughts, or info?
The ESM in other hand may not need grating. It needs radome and may need large spiral antenna or the array thereof . Those in gratings appear to be way too small and way too close to form baseline.Possibly an interferometry grating for ESM, specifically transmitter geolocation by assessing the phase angle delta between the wave front arriving at the individual holes.
Sure and I saw the modern one in the vid, but this conventional one just looks weird in those pics.While that is clearly a conventional helmet, some other J-20 footage shows the pilot wearing what looks a lot like a HMD. I guess there's little incentive to bring one along to a parade
Just found a different pic of it, posted by Deino on a hobby-forum 1 year ago. There he says it is a new helmet for use on the J-11B, J-15 and SU-35.I wouldn't read much into it.
Maybe. Didn't stop the F-22 from performing some crazy AIM-9 launches in testing. I'm guessing they're more limited by rail-launch. A missile coming off the rail under a 9G load is going to do weird things.Closed doors might also be better when maneuvering at supersonic speed, compared to opened doors.
If i am honest, in looks I prefer the F-22, i do not like the DSI intakes shape in general, so i do not like the looks of J-31, F-35 nor J-20 in general, i like the F-22 more if am really honest i am more retro, i love the F-14, well what i can expect I was born in 1971 and i fell in love with aviation when i saw pictures of F-14 and MiG-23 and the only few aircrafts i have ever really touched with my hands was an F-14 back in 2002 when the kitty hawk carrier was in Otaru Japan, and they left the public in general to visit the carrier during a friendly visit, it was great to touch F-14, but in reality the F-18 was more beautiful in close up .What a beauty. I like it's look better than any other produced 5th gen. It's what I expected the ATF would look like back in the mid 80s.
Video (Chinese):alert5.com said:J-20 test pilot Li Gang was invited to talk on a TV program by China’s CCTV. The episode was aired on Oct. 26.
Besides talking about the maiden flight on the J-20, which was given the callsign 787, Li also spoke on his role in assisting the flight testing of the J-10B TVC aircraft.
Li also talked briefly about the J-20’s anti-electromagnetic interference flight suit.
