Raytheon's Affordable Ground Based Radar (AGBR) Successfully Completes Testing

    TEWKSBURY, Mass., March 21, 2005  /PRNewswire/ -- Raytheon Company's
Affordable Ground Based Radar (AGBR) successfully completed all planned system
performance testing last month.

    This final milestone is the culmination of more than four years of working
with the Marine Corps to find the best solutions, utilizing engineering
innovation, development, integration and test activities sponsored by the
Office of Naval Research through contracts awarded by the U.S. Marine Corps
Systems Command to address the need for a highly mobile and transportable
multi-role radar system for the 21st century.

    A comprehensive test program conducted during the past six months was
recently completed on the AGBR Science & Technology concept demonstrator,
satisfying high level exit criteria and successfully demonstrating key
performance parameters such as mechanical setup and teardown, rotational
stability (at both 30 and 60 RPM), detection sensitivity, range and angular
accuracy, power consumption, doppler performance, dynamic range and more.

    The final testing included detection and tracking of calibrated targets in
the presence of a variety of simulated discrete and distributed clutter
environments.  The testing culminated with the successful tracking of a
training flight.  The jet provided the AGBR a controlled target with inbound
and outbound radial (as well as crossing) flight trajectories. The entire AGBR
test program was conducted at Raytheon's Surveillance and Sensors Center
located in Sudbury, Mass.

    The Marines envision fielding a multi-purpose radar to perform air
surveillance, air defense, ground weapons locating, and air traffic control.
Currently those four missions are each independently performed by aging legacy
radars designed for one single-purpose, using technology that is decades old.
The Marine Corps has designated this new development program as G/ATOR (Ground
/ Air Task Oriented Radar); the award of which is anticipated sometime in 2005
following a full and open industry competition. The successful AGBR test and
demonstration program will support the Marine Corps' anticipated G/ATOR
Milestone B Decision.
