are designations for a family of all-weather multimode airborne radar
systems designed by Hughes Aircraft
) for the F/A-18 Hornet
, and used on a variety of fighter aircraft
types. The APG-79
is an upgraded AESA
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 launch-and-leave 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... Read More
