The word RADAR is an acronym for RAdio Detection And Ranging, and in its simplest form it consists of a transmitted radio signal aimed by an antenna in a particular direction, and a receiver that detects the echoes off any objects in the path of the signal, he says.
The transmitter consists of an electronic circuit that osciallates at a specific frequency, usually much higher than those frequencies used for radio or TV broadcasts, says Brooker.
This signal is sent out in short bursts of electromagnetic energy, called pulses, through the antenna which produces a narrow beam like that of a torch.
"Radar makes it possible to determine the direction to an object, generally referred to as the target, based on the direction the antenna is facing," says Brooker.
The distance to the target is determined from the time taken between transmitting the pulse and receiving the echo. This can be accurately determined because the radar signal travels at the speed of light, which is constant.

RADAR -RADIO DETECTION AND RANGING SYSTEM
A system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects, by sending out pulses of radio waves which are reflected off the object back to the source.
