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.
The SPY-6 system consists of two primary radars and a radar suite controller (RSC) to coordinate the sensors. An S-band radar is to provide volume search, tracking, ballistic missile defense discrimination, and missile communications, while the X-band radar is to provide horizon search, precision tracking, missile communication, and terminal illumination of targets.

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.

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 N036 radar system is developed by Tikhomirov NIIP Institute and consists of a main nose-mounted X-band AESA radar with 1,514 T/R modules, designated the N036-1-01, and two smaller X-band AESA radars with 404 T/R modules (2,322 T/R modules total) mounted on the sides of the forward fuselage designated N036B-1-01.
