In contrast, the beam of a PESA radar can rapidly be changed to point in a different direction, simply by electrically adjusting the phase differences between different elements of the passive electronically scanned array (PESA). In 1959, DARPA developed an experimental phased array radar called Electronically Steered Array Radar (ESAR). It was ...
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.

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]
AN/APG-81 Northrop Grumman AESA radar for F-35 Lightning II; AN/APG-82 for F-15E Strike Eagle upgrades, originally proposed as AN/APG-63(V)4; AN/APG-83 SABR Northrop Grumman AESA radar for F-16V Block 70/72 Viper standard new production and upgrades; AN/APG-84 RACR Raytheon AESA radar for F-16 Fighting Falcon upgrades
The AN/APG-77 system itself exhibits a very low radar cross-section, supporting the F-22's stealthy design. [3] The upgraded APG-77(V)1 may have an even greater range. Much of the technology developed for the APG-77 was used in the AN/APG-81 radar for the F-35 Lightning II , and in turn the technology from the APG-81 was applied to the upgraded ...
On-board radar system with active phased array antenna, made with the same technology as Zhuk-AM, standardized for installation on different types of aircraft including drones. Can also be installed/carried in pods. Zhuk-AU/AUE comes in following versions: FGA 51.1 - A forward-looking "X" band AESA radar; FGA 51.2 - A side-looking "X" band AESA ...
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.
Saab Electronic Defence Systems (EDS) in May 2014 unveiled two new classes of active electronically scanned array (AESA) radar—three land-based systems (Giraffe 1X, Giraffe 4A and Giraffe 8A) and two naval variants (Sea Giraffe 1X and Sea Giraffe 4A) in X- and S-band frequencies—to complement its existing surface radar portfolio.
