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.

AN/APG-13 General Electric 75 mm nose gun aiming radar for North American B-25H Mitchell. AN/APG-14 S band gun aiming radar for Boeing B-29 Superfortress; AN/APG-15 S band tail gun aiming radar for Boeing B-29B Superfortress and Consolidated PB4Y Privateer; AN/APG-16 improved AN/APG-2 gun aiming radar for B-32.
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 ...
While the first tests were made with US-made transmitter-receivers, the current radar features parts manufactured by Thales. The radar uses about 838 GaAs T/R modules. In July 2004, DGA awarded a 90 million-euro contract for the development of a second a AESA radar demonstrator. Production of the RBE2-AA commenced in 2008 and entered service in ...
The AN/SPY-1 [a] is a United States Navy passive electronically scanned array (PESA) 3D radar system manufactured by Lockheed Martin, and is a key component of the Aegis Combat System. The system is computer controlled and uses four complementary antennas to provide 360-degree coverage.
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.
AESA antenna of the Sea Giraffe 4A on board HTMS Bhumibol Adulyadej. In May 2014, Saab Electronic Defence Systems (EDS) 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).
