A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] 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.
Mobile doppler weather radars have been used on dozens of scientific and academic research projects from their invention in the late 1900s. [1] One problems facing meteorological researchers was the fact that mesonets and other ground-based observation methods were being deployed too slow in order to accurately measure and study high-impact atmospheric phenomena.

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.).
Pulse-Doppler radar can reduce clutter by over 60 dB, which can allow objects smaller than 1-square-foot (0.093 m 2) to be detected without overloading computers and users. Systems using pulse-Doppler signal processing with speed rejection set above the wind speed have no clutter zone. This means that the clear region extends all the way to the ...
