Active Electronically Scanned Array

Here are the list of AESA use in aircraft:

Northrop Grumman/Raytheon AN/APG-77, for the F-22 Raptor
Northrop Grumman AN/APG-80, for the F-16E/F Block 60 Fighting Falcon
Northrop Grumman AN/APG-81, for the F-35 Joint Strike Fighter
Northrop Grumman Multi-role AESA, for the Boeing Wedgetail (AEW&C)
Northrop Grumman APY-9, for the E-2D Advanced Hawkeye
Northrop Grumman SABR, for F-16 Fighting Falcon upgrades
Raytheon AN/APG-63(V)2 and AN/APG-63(V)3, for the F-15C Eagle and Republic of Singapore's F-15SG
Raytheon APG-79, for the F/A-18E/F Super Hornet and EA-18G Growler
Raytheon AN/APQ-181 (AESA upgrade currently in development), for the B-2 Spirit bomber
AMSAR, research from the European GTDAR consortium, for Eurofighter and Rafale fighter Radar
Captor-E CAESAR (CAPTOR Active Electronically Scanning Array Radar)

No wonder Singapore Air Force choosed F15SG over others 4th generation aircraft fighter... AESA is one of the main reason( at that time la).
