The AN/APG-65 radar is a highly reliable, flexible system used for both air-to-air and air-to-surface missions.
The key to the APG-65's flexibility is its programmable digital computers. The built-in test system provides total end-to-end radar preflight checkout and continuous monitoring. During air-to-air operations, the APG-65 radar incorporates clean scope, look-down/shoot-down capabilities. It also features complete search track and automatic acquisition modes such as high pulse repetition frequency (PRF) velocity search, high/medium PRF range-while-search, single target track, and a track-while-scan mode that tracks 10 targets simultaneously and displays eight targets.
For air-to-surface operations, the radar provides Doppler beam sharpened sector and patch mapping, medium-range synthetic aperture radar, "real beam" ground mapping modes, as well as fixed and moving ground target track, air-to-surface ranging, terrain avoidance, precision velocity update, and a sea surface search mode with clutter suppression.
The APG-65 is operational in the F/A-18 Hornet F/A-18 A/B/C/D strike fighters of the U.S. Navy and Marine Corps, and the air forces of Kuwait, and Spain. It has been adapted to upgrade the German and Greek F-4 Phantom aircraft and AV-8B Harrier II Plus for the U.S. Marine Corps and the Spanish and Italian navies.
