Multi-role Electronically Scanned Array
L band |
The Multi-role Electronically Scanned Array (MESA) is an active electronically scanned array surveillance radar system for the Boeing E-7 Wedgetail airborne early warning and control aircraft. The radar is produced by Northrop Grumman.
Design and development
In the 1990s, Australia recognized a need for an airborne early warning and control (AEW&C) aircraft. In 1996, Australia issued a request for proposal (RFP) for the aircraft for the RAAF under Project Wedgetail, referring to the Wedge-tailed eagle.[1] In 1999, Australia awarded Boeing Integrated Defense Systems a contract to supply four AEW&C aircraft with options for three additional aircraft.[citation needed]
The
The 10.8 m long by 3.4 m high antenna assembly incorporates 7.3 m long by 2.7 m high Side-Emitting Electronic Manifold array, with the top hat supporting array providing 120° coverage on port and starboard side, while the top hat array itself provides 60° fore and aft, thus providing a complete 360° coverage. The radar's beam can be set for a 2° to 8° width, while scan duration can be set from 3 s to 40 s. Radar signal processing equipment and central computer are installed directly below the antenna array.[3]
The cabin features eight operator consoles with sufficient space for four more; the Australian fleet will operate ten consoles with space for two more (four on starboard side and six on the port side).[4]
