Radar AESA GaN Tech vs. Radar AESA GaAs Tech !
what the difference between both of type radar AESA ?
AN/APG-63(V)2 is a AESA GaAs
APG-63(V)3 is a AESA GaN
I have heard that AESA GaN has jamming capability, lower power consumption, the range farther, less heat output than AESA GaAs. Does anyone have any comments?

[Blackadam] The J/APG-1 is an active phased array radar developed to equip the Japanese Air Self-Defense Force (JASDF) F-2 fighter aircraft. The J/APG-1 radar only has a detection range of 40 kilometers due to problems caused by the interferences coming from the interaction of the body and the radar’s antenna. This radar system entered service with the F-2 jet in 2002.
That was what performance was rumoured to be when it was first put into service in 2000, without being fully developed. 2002 may have been when the glitches had been ironed out. AFAIK the Japanese haven’t published range figures.

The first radar AESA JAPG 1 is a very short range detect. Comparison it to the first radar PESA Zaslon’s MiG-31,
Next comparsion, a fishing trawler with the USS Gerald Ford…
they are both boats…

What are you trying to state here ?
Iam surprised that you still have to ask that question. Ever since he been in this forum, he always find the sources with the lowest performance value for Western equipments, highest performance value for Russian, then make some ridiculous comparison to justify his Russia STRONK narrative.It getting so old now.

Anyway comparing J/APG-1 with Zaslon is bit overstretched. Despite being AESA J/APG-1 clearly does not have 1.1 m diameter antenna of MiG-31. Thus comparison is simply useless.

The MiG-31 was the world’s first operational fighter with a passive electronically scanned array radar (PESA), the Zaslon S-800. Its maximum range against fighter-sized targets is approximately 200 km (125 mi), and it can track up to 10 targets and simultaneously attack four of them with its AA-9 ‘Amos’ missiles. It is claimed to have limited astern coverage, possibly due to drag chute housing above and between the engines. The radar is matched with an infrared search and tracking (IRST) system in a retractable undernose fairing.
