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 ...
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 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]
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 ...
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 ...
Agile radars like AESA (or PESA) can change their frequency with every pulse (except when using doppler filtering), and generally do so using a random sequence, integrating over time does not help pull the signal out of the background noise. Moreover, a radar may be designed to extend the duration of the pulse and lower its peak power.
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 ...
