Background
Radar, a transliteration of radio in english, is derived from the acronym of radiodetectionandranging, meaning "radio detection and ranging", i.e. finding objects and determining their spatial position by radio. Therefore, radar is also referred to as "radiolocation". Radars are electronic devices that detect objects using electromagnetic waves. The radar emits electromagnetic waves to irradiate a target and receives the echo of the target, so that information such as the distance from the target to an electromagnetic wave emission point, the distance change rate (radial speed), the azimuth and the altitude is obtained. The radar functions similarly to the eyes and ears, and of course, it is no longer a natural task, and its information carrier is a radio wave. In fact, whether visible light or radio waves are essentially the same thing, they are electromagnetic waves, and the speed of propagation in a vacuum is the speed of light C, the difference being that their respective frequencies and wavelengths are different.
