How did you gather that packing similar number of T/R modules = Chinese radar tech is on par with US?
The basic premise that all things being equal.

In my opinion the quality, the speed (of switching) and the power output of T/R module matters more than packing more T/R module into the same confine space. Let me illustrate my point - it is like the old passive matrix LCD (remember those?) vs quantum dot technology that just came out this year - they might do the same thing but the power efficiency, brightness, reliability and longevity are on whole different level.
If you are making a claim that the technological base is more advance, you need to provide a posteriori evidence in support.

Well, if we talking about comparable radar sizes then a similiar amount of T/R modules would highly imply a comparable level of radar technolgy.

Thanks for posting, however the huge image showing 2015 was posted already yesterday and the second one You gave a link seems to be the same albeit with the red signs psed-away (in the center of the image on that small red cornerstone the red is still there !)

Anyway a nice family portrait !

It seems that they have already installed functional EOTS on J-20 coz earlier prototypes only had mockup EOTS, and if it's real its a major breakthrough for them. It would definitely give them situational awareness at least on par with F-35.

That's not something we can say given we have no idea what sensors J-20 has in total let alone how good they are and how well they're integrated for the pilot to consume nor how that compares to F-35, however having an EOIRST will definitely help J-20's passive sensor capability.

Welcome to the forum.

How did you established that it is functional? In comparison, it is still questionable after many years of development that the F-35 has achieved the situational awareness as planned. Central to such capability is the integration and fusion of sensors through the underlying software which is known to be still under development.

As you could see when 2013 prototype flew for the first time it had this cone under the nose but it could easily be identified that it was only a mockup. when you see the 2015 prototype it definitely has functional EOTS installed, but to what degree it's been developed or how far down the line they are in development that's questionable not only for J-20 but for F-35 as well. As we all could see it they are certainly far ahead in terms of in terms of development than we could have ever thought.We all know that F-35 was ahead in development but it doesn't necessarily guarantees it would be the first one to accomplish the sensor fusion integration or the kind of data it could relay to pilots through software which is still under development which is still giving them lot of headche.

How do you conclude something is functional as in this case by visual assessment? I am curious. .
but to what degree it's been developed or how far down the line they are in development that's questionable not only for J-20 but for F-35 as well. As we all could see it they are certainly far ahead in terms of in terms of development than we could have ever thought.
You said it is unknown how far the development is but yet it is certainly far ahead in terms of expected development. How do you rationally make such conclusion?

We all know that F-35 was ahead in development but it doesn't necessarily guarantees it would be the first one to accomplish the sensor fusion integration or the kind of data it could relay to pilots through software which is still under development which is still giving them lot of headche.
No one is making that suggestion. Firstly, what exactly is situalional awareness in the F-35 is not exactly well defined. If you know, I would be glad to be educated. Likewise, if you know what is in the J-20 program, I would similarly be glad to be educated.
