An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).
A fire-control radar (FCR) is a radar that is designed specifically to provide information to a fire-control system in order to direct weapons such that they hit a target. They are sometimes known as narrow beam radars, targeting radars, tracking radars, or in the UK, gun-laying radars. If the radar is used to guide a missile, it is often known as a target illuminator or illuminator radar.
The AN/APG-66 radar is an X-band solid state medium range pulse-Doppler planar array radar originally designed by the Westinghouse Electric Corporation for use in early generations of the F-16 Fighting Falcon. Later F-16 variants use the AN/APG-68 or the AN/APG-83. This radar was employed in all domestic and export versions of the F-16A/B models throughout the production. Subsequent upgrades have been installed in many varying aircraft types including the U.S. Customs and Border Protection's C-550 Cessna Citation, US Navy P-3 Orion, and Piper PA-42 Cheyenne II's.
The AN/APG-63 and AN/APG-70 are a family of all-weather multimode radar systems designed by Hughes Aircraft for the F-15 Eagle air superiority fighter. These X band pulse-Doppler radar systems are designed for both air-air and air-ground missions; they are able to look up at high-flying targets and down at low-flying targets without being confused by ground clutter. The systems can detect and track aircraft and small high-speed targets at distances beyond visual range down to close range, and at altitudes down to treetop level. The radar feeds target information into the aircraft's central computer for effective weapons delivery. For close-in dogfights, the radar automatically acquires enemy aircraft and projects this information onto the cockpit head-up display. The name is assigned from the Army Navy Joint Electronics Type Designation System.
The AN/APG-65 and AN/APG-73 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 version.
The AN/APG-79 is a type of active electronically scanned array (AESA) radar that was developed for use on the United States Navy's Boeing F/A-18E/F Super Hornet and Boeing EA-18G Growler aircraft. The radar's AESA technology provides quick updates on multiple targets, and its solid-state antenna construction makes it more reliable and cost-effective than traditional radar systems. The radar has a range of up to 150 km and can track multiple targets simultaneously. It is capable of firing weapons such as the AIM-120 AMRAAM's D model and guiding multiple missiles to targets located at varying distances and directions. As of July 2008, 100 APG-79 sets had been delivered to the United States Navy, and the Navy expects to order around 437 production radars. In January 2013, the Director, Operational Test & Evaluation (DOT&E) disclosed some issues with the APG-79 radar during its initial operational testing, but upgrades have been made over time.
The AN/APG-68 radar is a long range Pulse-doppler radar designed by Westinghouse to replace AN/APG-66 radar in the F-16 Fighting Falcon. After years of Service, AN/APG-68 radar currently being replaced on US Air Force F-16C/D Block 40/42 and 50/52 by the latest generation AN/APG-83 AESA radar.
The AN/APG-77 is a multifunction low probability of intercept radar installed on the F-22 Raptor fighter aircraft. The radar was designed and initially built by Westinghouse and Texas Instruments, and production continued with their respective successors Northrop Grumman and Raytheon after acquisition.

The AN/APG-67 is a multi-mode all-digital X band coherent pulse doppler radar originally developed by General Electric for the Northrop F-20 Tigershark program of the early 1980s. It offers a variety of air-to-air, air-to-ground, sea-search and mapping modes, and compatibility with most weapons used by the US Air Force in the 1980s.
A large number of variants of the General Dynamics F-16 Fighting Falcon have been produced by General Dynamics, Lockheed Martin, and various licensed manufacturers. The details of the F-16 variants, along with major modification programs and derivative designs significantly influenced by the F-16, are described below.
The AN/APG-83 Scalable Agile Beam Radar (SABR) is a full-performance active electronically scanned array (AESA) fire control radar for the General Dynamics F-16 Fighting Falcon and other aircraft developed by Northrop Grumman. In a 2013 competition, Lockheed Martin selected SABR as the AESA radar for the F-16 modernization and update programs of the United States Air Force and Republic of China Air Force.
The AN/SPY-6 is an active electronically scanned array 3D radar under development for the United States Navy (USN). It will provide integrated air and missile defense for Flight III Arleigh Burke-class destroyers.
