AN/APG-65 radar family
The AN/APG-65 and AN/APG-73 are designations for a family of all-weather multimode airborne radar systems designed by Hughes Aircraft (now Raytheon) for the F/A-18 Hornet, and used on a variety of fighter aircraft types. The APG-79 is an upgraded AESA version.
These I band (8 to 12 GHz) pulse-Doppler radar systems are designed for both air-to-air and air-to-surface missions. For air-to-air operations they incorporate a variety of search, track and track-while-scan modes to give the pilot a complete look-down/shoot-down capability. Air-to-surface modes include Doppler beam sharpened sector and patch mapping, medium range synthetic aperture radar, fixed and moving ground target track and sea surface search. In the F/A-18, the radar is installed in a slide-out nose rack to facilitate maintenance.

The APG-65 was developed in the late 1970s and has been operational since 1983. The radar includes a velocity search (to provide maximum detection range capability against nose aspect targets), range-while-search (to detect all-aspect targets), track-while-scan (which, when combined with an autonomous missile such as AIM-120, gives the aircraft a fire-and-forget capability), single target track, gun director and raid assessment (which enables the operator to expand the region centred on a single tracked target, permitting radar separation of closely spaced targets) operating modes.
Although no longer in production, the APG-65 remains in service in F/A-18 Hornet strike fighters of the U.S. Navy and Marine Corps, and the air forces of Canada, Australia, Kuwait, and Spain. It has also been adapted to upgrade the German and Greek F-4 Phantom aircraft, and the AV-8B Harrier II Plus for the U.S. Marine Corps and the Spanish and Italian Navies.
