Any electromagnetic device that detects and locates a target by radiating electromagnetic energy and uses the echos scattered from a target can be classified as a radar, regardless of its frequency. Radars have operated at frequencies from a few megahertz to the ultraviolet region of the electromagnetic spectrum .
Read moreHow does radar work in aviation?
A radar system detects other aircraft, ships, or other objects and the speed and direction in which they travel by sending out a pulse of high-frequency electromagnetic waves . This pulse goes out ahead of the aircraft until it encounters an object and reflects off of it.
Read moreWhat is radar and how it works?
RADAR is fundamentally an electromagnetic sensor used to detect and locate objects . Radio waves are radiated out from the radar into free space. Some of the radio waves will be intercepted by reflecting objects (targets). The intercepted radio waves that hit the target are reflected back in many different directions.4 Kas 2021
Read moreHow does a radar detect?
Radar (radio detection and ranging) is a detection system that uses radio waves to determine the distance (ranging), angle, and radial velocity of objects relative to the site .
Read moreWhat is the maximum range of radar?
Therefore, the maximum range of Radar for given specifications is 158KM .
Read moreHow far can radar detect?
This permits target detection at distances from about 500 to 2,000 nautical miles (900 to 3,700 km) . Thus, an HF over-the-horizon (OTH) radar can detect aircraft at distances up to 10 times that of a ground-based microwave air-surveillance radar, whose range is limited by the curvature of the Earth.
