AMSAR

Thursday, November 25, 2010

AMSAR is an Active Electronically Scanned Array radar, which has just been developed by the British/French/German GTDAR consortium. "AMSAR" is the acronym for Airborne Multirole Solid State Active Array Radar. It consists of a fixed antenna and up to 2,000 gallium arsenide, monolithic microwave integrated circuit transceiver modules which provides independent control of phase and amplitude and a multibeam capability. The level of beam agility features simultaneous air-to-air, air-to-ground, terrain following and terrain avoidance operating modes. AMSAR also provides multiple jammer nulling, stealthy functionality, low probability-of-intercept (low sidelobes), multistatic operation and a wide bandwidth.

The AMSAR project began in 1993 in a 50/50 Anglo-French programme with German technical participation. The radar is envisaged as a replacement for the Typhoon's CAPTOR radar and the Rafale's RBE2 passive electronically-scanned-array.
