The simplest radar gun consists of a radio wave transmitter and receiver. The transmitter sends out a radio wave signal, and the receiver accepts the part of the signal that is reflected by the object being measured. If the measured object has a relative speed to the radar gun, the frequency of the signal it reflects will change. The radar gun calculates the speed of the object based on this frequency change. ^[1]

The radar gun was invented in March 1954, and was first used in the United States in April of the same year.

There are devices on the market that can feel the radar and laser guns used by police, just like in
