I feel your pain man, I’m getting tired of reposting the other images of the aircraft in question I found 😀
😀
APG-63(V)2
😎 How about this combo?

Oh…………and…………….back to the topic
..
More from CDF
Got this from CDF
PL-9C
PL-5E
TY-90
PL-9 supposed to have input from PL-8 and R-73 (Can anyone confirm?).
F/A-22, FB-22 maybe F-35A :cool::cool:
PAK-FA, Su-34
XXJ(J-12???), J-10C
PAK-FA, MCA, LCA
PL-7
PL-8
PL-9

I think thats the PL-7 (Magic look alike)
Awww No probs 🙂
Just some AESA radars
1). APG-77 (F/A-22)
The heart of the F-22’s electronics capabilities is the “APG-77” radar system, though it is so much more than a radar that some prefer to call it a “multifunction RF system” instead.
With the APG-77, the F-22 will be able to detect an enemy aircraft’s radar from distances of up to 460 kilometers (250 nautical miles). It will be able to acquire an enemy aircraft with radar at distances of up to 220 kilometers (125 nautical miles), while its “low probability of intercept” radar signal will be very difficult to detect and the “stealthy” F-22 will remain invisible to the enemy’s radar.
Once AIM-120 Extended Range Air To Air Missiles (ERAAM) are available, the F-22 will be able to destroy that enemy at a range of 185 kilometers (100 nautical miles). In many cases, the enemy will be hit without warning.
The APG-77 is built around an “Active Electronically Scanned Array (AESA)”, which consists of an array of about 2,000 transmitters-receiver (T/R) modules that are linked together by high-speed processors. The AESA can obtain electronics intelligence; jam enemy electronic systems; provide surveillance; and perform secure voice and datalink communications, all that the same time. The AESA can simultaneously emit several tight beams to perform different functions. “Anything that can be done with X-band RF can be done with that antenna,” one program official commented.
Although the Air Force considered auxiliary side-mounted arrays for the APG-77, they were abandoned due to cost, and the AESA is limited to a field of view 120 degrees across in the forward direction. Other antennas provide missile and radar warning behind the aircraft.
When operating as a radar, the APG-77 transmits waveforms that change from burst to burst, and are sent at random frequencies. Such a changing signal is very difficult for an enemy to detect and analyze. If the enemy does manage to detect the signal, he or she must then try to get a radar lock on the F-22 so it can be attacked. The F-22’s stealthiness makes this tricky in the first place, but to make matters more troublesome, the AESA also analyses the enemy’s radar and sends out a jamming burst to disrupt the lock. The AESA then goes on to other tasks until the enemy radar begins its lock cycle again.
The APG-77 is not intended to give the F-22 a “standoff jamming” capability, such as that provided by electronic warfare aircraft like the Grumman EA-6B Prowler, blinding enemy radars over wide areas on a continuous basis. The APG-77’s mission is mainly to allow the F-22 to fight effectively while remaining difficult to detect. A standoff jamming platform, in contrast, can’t help but advertise its presence.
Between dealing with active threats, the AESA collects information on the “electronic order of battle (EOB)” in the operational area, locating electronic systems, classifying them, and alerting the pilot to possible threats or high-priority targets.
