A radar gun or speed gun is a device used to measure the speed of different objects. It might by a traffic officer to clock a vehicle's speed. Or perhaps a TV network is using it to clock a Baseball pitcher's fast ball. The applications vary, but the unit works by applying the Doppler effect to discover how fast something is going. Basically, the unit sends out a signal and looks at the return signal. It compares the frequency of the returned signal to the transmitted one, and the difference can be "converted" into a speed.
