Radar is the use of electromagnetic waves to identify the range, system height, direction and speed, moving and fixed objects such as airplanes, ships, cars, weather formation, and terrain. This term is used as an abbreviation for radar radio detection and ranging in 1941.
The use of radio waves to detect the presence of distant metal objects was first of all to Christian Hü Balsmer, who in 1904 showed the feasibility of detecting the presence of a ship in dense fog, not its distance. 1934, very É-mile, working with the French first radar system, said that he established a radar system envisioned according to Tesla's principles
The radar system has a transmitter that emits radio waves that are reflected by the target and detected by the receiver, typically at the same location. Although the returned signal is very weak, the signal can be amplified. This makes the radar detection range, other emissions, such as sound or visible light, too weak to detect. Modern radar systems are highly complex and produce detailed information on fixed and moving objects. Radar is used in many cases, including precipitation meteorological detection, measurement of ocean surface waves, air traffic control, high-speed traffic police detection, and military.
