Doppler

A Doppler Radar uses the Doppler effect of returned echoes from certain objects to measure their radial velocity. They are used for various things including air traffic control, police speed guns, and air defense. Here is a photograph from a Doppler Radar of Hurricane Andrew that hit Miami and caused extreme damage.
