The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. 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.

Arudhra MPR - Static 4D AESA Medium power radar for airspace surveillance for ranges exceeding 300 km. ADTCR - Mobile 4D AESA Medium power radar for airspace surveillance Ashwini LLTR - Mobile 4D AESA radar for Low level air targets up to ranges of 200 km.
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. [2] The radar has a range of up to 150 km (80 nm) and can track multiple targets simultaneously. [3]
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. [2] The capabilities of this advanced AESA are derived from the F-22's AN/APG-77 and the F-35's AN/APG-81.
The F-22 radar from Lot 5 aircraft onward is the APG-77(V)1, which draws heavily on APG-81 hardware and software for its advanced air-to-ground capabilities. [5] In August 2005, the APG-81 radar was flown for the first time aboard Northrop Grumman's BAC 1–11 test aircraft. The radar system had accumulated over 300 flight hours by 2010.
The radar development began in 2012 and its full-scale model was displayed at the 2017 Aero India air show and aviation exhibition. [2] A fully functional active electronically scanned array (AESA) radar prototype was unveiled at Aero India 2019, the prototype was mounted inside the glass nose of a HAL Tejas prototype.
The AN/APG-85 is an active electronically scanned array (AESA) radar system designed by Northrop Grumman for the Lockheed Martin F-35 Lightning II.The AN/APG-85 is a further development of the AN/APG-81 and is planned to be installed in all three variants of the F-35 aircraft from Lot 17 and onwards, which are planned to enter production in 2025.
The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar first produced by GE Aerospace in 1980 and now part of Lockheed Martin. [1] [2] The system offers instrumented detection at ranges on the order of 200 to 250 nautical miles (370 to 460 km; 230 to 290 mi) and has a wide variety of interference and clutter rejection systems.
