Continuous wave radar (CW radar) is not the only form
of radar able to make use of the Doppler effect.
Doppler shifts can be used in pulse radar, as they
were in CW radar, to determine the relative velocity of
moving targets. Pulse radars designed to make use of the
Doppler effect in this way are called pulse Doppler radar (PD radar).
Pulse doppler radars are very useful radar
systems as they combine their ability to determine target velocity
with the other functionality of a standard pulse radar. A
pulse doppler radar can, therefore, determine range, angle
and velocity of a target. This makes pulse doppler radar extremely valuable in situations involving many small moving
targets hidden by heavily cluttered environments. A maritime scenario involving
low-flying aircraft and anti-ship missiles is an example of such
It is common for pulse doppler radars to have
a capability to concentrate only on moving targets, removing the
sometimes confusing clutter from the operatorís display. This capability is
called moving target indication (MTI).
