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. [1]
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 ...
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.
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/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 ...
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]
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 Type 052C destroyer (NATO/OSD Luyang II-class destroyer) is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy Surface Force (PLAN). The Type 052C introduced both fixed active electronically scanned array (AESA) radar and vertically launched surface-to-air missiles into PLAN service, [6] making it the first Chinese warship with area air defence capability.
