Radar that employs the shift in frequency of radio waves returned from moving objects in order to give the objects' speed. Thus, the radar can detect the motion of individual air parcels, raindrops, fronts, or storms.
A type of radar which uses the Doppler effect to calculate velocity of precipitation targets toward or away from the radar.
The weather radar system that uses the Doppler shift of radio waves to detect air motion that can result in tornadoes and precipitation, as previously-developed weather radar systems do. It can also measure the speed and direction of rain and ice, as well as detect the formation of tornadoes sooner than older radars.
