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 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.
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 ...
Ashwini LLTR - Mobile 4D AESA radar for Low level air targets up to ranges of 200 km. INDRA series of 2D Pulse-doppler medium range airspace surveillance radars; Rajendra 3D medium range PESA fire control radar for Akash SAM. Central Acquisition Radar (3D-CAR) PESA tracking radar for battlefield surveillance as part of the Akash SAM system.
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 ...
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 Type 346 was developed by the Nanjing Research Institute of Electronics Technology [nb 1] Further development may have been assisted by the examination of foreign technology; the Type 051C destroyers used 30N6EI Tombstone phased-array Flap Lid antennae from Russia, and in 2004 a prototype C band active phased-array radar and its design package were purchased from the Kvant Design Bureau of ...
