Doppler Radar (from Wikipedia.org)
A Doppler radar is a specialized radar that makes use of the doppler effect
to produce velocity data about objects at a distance. It does this by beaming
a microwave signal towards a desired target and listening for its reflection,
then analyzing how the frequency of the returned signal has been altered by
the object's motion. This variation gives direct and highly accurate measurements
of the radial component of a target's velocity relative to the radar. Doppler
radars are used in aviation, sounding satellites, meteorology, police speed guns,
radiology, and bistatic radar (surface to air missile).
