Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).https://en.wikipedia.org/wiki/Weather_radar
Radar basics and the doppler shift. NEXRAD (Next Generation Radar) obtains weather information (precipitation and wind) based upon returned energy. The radar emits a burst of energy (green in the animated image). If the energy strikes an object (rain drop, snowflake, hail, bug, bird, etc), the energy is scattered in all directions (blue).
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.

A positive phase shift implies motion toward the radar and a negative shift indicates motion away from the radar. Doppler radar sends the energy in pules and listens for any returned signal. The phase shift effect is similar to the "Doppler shift" observed with sound waves.
