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.

The tornado was on the ground for approximately 25 minutes and became rain-wrapped at one point, eventually roping out and dissipating. The tornado stayed in open rural areas and damaged only a few trees and telephone poles. It was rated EF2 on the Enhanced Fujita Scale based upon Doppler weather radar measurements. [125]
Microwave Doppler frequency shift produced by reflector motion falls into the audible sound range for human beings (20–20 000 Hz), which is used for target classification in addition to the kinds of conventional radar display used for that purpose, like A-scope, B-scope, C-scope, and RHI indicator. The human ear may be able to tell the ...
