The AN/APG-80 is a synthetic aperture radar (SAR) system designed to perform continuous search and to track multiple targets within the forward hemisphere of the aircraft. Developed and manufactured by Northrop Grumman for use on the F-16 Fighting Falcon fighter aircraft, the AN/APG-80 is an agile beam fire control radar which include much greater detection range, high-resolution synthetic aperture radar imagery, and a two-fold increase in reliability compared to conventional, mechanically scanned radars. It is sometimes referred to as an active electronically scanned array system. It became operational in 2003.
The AN/APG-80 can perform air-to-air, search-and-track, air-to-ground targeting and aircraft terrain-following functions simultaneously and for multiple targets. As a SAR system utilizing NG's fourth-generation transmitter/receiver technologies, it has a higher reliability and twice the range of older, mechanically-scanned AN/APG-68 radar systems.
