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.

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.
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/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.
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/APG-81 is an active electronically scanned array (AESA) fire-control radar system designed by Northrop Grumman Electronic Systems (formerly Westinghouse Electronic Systems) for the Lockheed Martin F-35 Lightning II. [1] The AN/APG-81 is a successor radar to the F-22's AN/APG-77, and has an antenna composed of 1,676 transmit/receive modules.
Is a development of Phazotron's first PESA radar Zhuk-F for original MIG-35. The RP-35 adopts the traditional linear radar field distribution typical among most PESA radars. [5] The radar can simultaneously track 24 targets with a range against a 3 m 2 RCS target 140 km head on, 65 km pursuit. [5]
