The following information is about Radar.
Radar Defined
Radar (radio detection and ranging), system or technique for detecting the position, motion, and nature of a remote object by means of radio waves reflected from its surface. Radar systems transmit pulses of electromagnetic waves by means of directional Antennas; some of the pulses are reflected by objects in the path of the beam. Reflections are received by the radar unit, processed electronically, and converted into images on a Cathode-Ray Tube. The distance of the object from the radar source is determined by measuring the time required for the radar signal to reach the target and return. The direction of the object with respect to the radar unit is determined from the direction in which the pulses were transmitted. In most units, the beam of pulses is continuously rotated at a constant speed, or it is scanned (swung back and forth) over a sector at a constant rate. The velocity of the object is sometimes determined by the Doppler Effect: if the object is approaching the radar unit, the frequency of the returned signal is greater than the frequency of the transmitted signal; if the object is receding, the returned frequency is less; and if the object is not moving relative to the radar unit, the frequency of the returned signal is the same as the frequency of the transmitted signal. Most radar units operate on microwave frequencies.
