What is the principle of radar?

The basic principle behind radar is simple – extremely short bursts of radio energy (traveling at the speed of light) are transmitted, reflected off a target and then returned as an echo . Radar makes use of a phenomenon we have all observed, that of the ECHO PRINCIPLE.

Radars today are used to detect and track aircraft, spacecraft, and ships at sea as well as insects and birds in the atmosphere; measure the speed of automobiles; map the surface of the earth from space; and measure properties of the atmosphere and oceans.

Radar is a device that uses reflected radio waves to detect the position or movement of a person or thing . An example of radar is the device highway patrol officers use to detect people who are driving too fast.

RADAR stands for Radio Detection and Ranging System. It is basically an electromagnetic system used to detect the location and distance of an object from the point where the RADAR is placed . It works by radiating energy into space and monitoring the echo or reflected signal from the objects.

radar, electromagnetic sensor used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distances . It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, and observing the echoes returned from them.
