CW Doppler Tri-Fold (.pdf) - ESD Radar - Home

BAE Systems CW Doppler Radar is an
advanced tracking radar that provides
accurate TSPI data on a variety of noncooperative
targets. Primarily intended for
tracking ballistic targets, it is also capable
of providing highly accurate track data on
other types of targets including rockets,
missiles and aircraft at long ranges. With
the addition of the Multi-Frequency Ranging
(MFR) option, the Radar can make direct
range measurements on moving targets,
adding another dimension to the
capabilities of Doppler radar.
The CW Doppler Radar provides a direct
measurement of target radial velocity and
target range (with MFR option) in “real
time”; also performs active “real time”
tracking of rockets, mortars, bombs, and
conventional munitions.
BAE Systems CW Doppler Radar provides
fast acquisition and track capability and can
be integrated into the range data network.
The CW Doppler system provides accurate
slaving data for other radar systems and
sensors ensuring a positive track on even
the most uncooperative targets.
Available in S-band, C-band and X-band
versions, with optional frequency
adjustment within the band to avoid
interference with other systems.
