Northrop-Grumman has completed initial testing of the first production Multirole
Electronically Scanned Array, MESA, radar antenna for Australia's Wedgetail AEW&C
The MESA exploits leading-edge technology by combining two side-looking phased
arrays with an innovate end-firing "top-hat" antenna that emits and shapes a
beam in the fore and aft directions. This combination makes MESA the first
airborne surveillance radar that provides a 360-degree azimuth scan without
mechanical rotation of a radar dish.
The MESA will be integrated into a modified Boeing 737-700 aircraft. The first
of these platforms rolled off the factory in October 2002, Australian Defense
Forces has purchased a total of 4 aircraft.
MESA radar, constructed of ultralight material, will be attached to the top aft
section of the B737-700 fuselage. MESA enables state-of-the-art performance at a
fraction of current systems weight and allowing more time on station for the
Wedgetail program calls for a multirole surveillance platform, MESA using pulse
Doppler radar forms for air search and pulse forms for maritime surface search.
In Addition, MESA will provide integrated civil and military IFF capability.
The first flight of a MESA-equipped 737-700 is scheduled for early 2004.
