How does a radar work?



  1. 0 Votes

    Radar works by emitting electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations, and terrain. The term RADAR was coined in 1941 as an acronym for radio detection and ranging. It is the same principle as bats use for echo location. By emitting a set frequency noise, they can tell the position of other objects around them by the surroundings altering the sound and reflecting it to a certain perception.
