What is the definition of radar?
Stands for radio detecting and ranging. Radar uses electromagnetic waves in the radio or microwave frequency spectrum to detect and measure the distance to objects or surfaces through wave reflection and detection.
Radar uses a high-accuracy timing device to measure how long it takes from the time that the emitted electromagnetic radiation to travel both to and from the object or surface. Using this duration and the speed of the radiation, the range can be accurately calculated.
