Was Surfing the web when I came across this article on the j20's AESA radar written by china aerospace studies institute which uses a 2016 Weibo article as a source . How credible/accurate is this report?
TLDR:
-Article suggest j20 radar upgraded beyond capacity of type 1475 (KLJ-5) radar
-j20 now has the capability to integrate 2200 modules
-detection range is 120 miles compared to f35s 80 miles
-quoted from the article which quoted from Pakistan defence forum
"With a high number of T/R modules, the Type 1475 would be vulnerable to radar warning
receiver (RWR) systems such as the ALR-94 without a very capable low probability intercept
(LPI) mode.… Even if the Nanjing Research Institute of Electronics Technology (NRIET) or the
China Leihua Electronic Technology Research Institute (607 Institute) was able to develop
sufficient packaging technology that would enable 1,856 T/R modules within the J-20's nose, the
density of the T/R modules would create significant cooling problems,”
