Doppler Radar maps are constructed, often by meteorologists, by making use of satellite imagery and the Doppler radar effect. This specialized radar uses microwave signals to produce velocity data about a desired object at a distance. The reflection is noted and analyzed from the feedback of the microwave and a signal is returned to a radar giving information about the object's motion. This variation is highly accurate and is used most commonly for meteorological purposes as in the mapped image below of weather patterns in the south eastern United States, but is also employed for uses in radiology, aviation, and police speed guns.
