radar, microwave radar, radio detection and ranging, radiolocation(noun)
measuring instrument in which the echo of a pulse of microwave radiation is used to detect and locate distant objects
The method of detecting objects, finding their distance, or determining their speed, by use of a radar device; as, modern radar can detect objects as small as raindrops.
Origin: [acronym from RAdio Detection And Ranging.]
A method of detecting distant objects and determining their position, velocity, or other characteristics by analysis of sent radio waves (usually microwaves) reflected from their surfaces
A type of system using such method, differentiated by platform, configuration, frequency, power, and other technical attributes.
An installation of such a system or of the transmitting and receiving apparatus.
A superior ability to detect something.
His sensitive radar for hidden alliances keeps him out of trouble.
To scan with radar, or as if with radar.
Origin: Originally spelled RADAR; an acronym of .
Radar is an object detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio waves or microwaves which bounce off any object in their path. The object returns a tiny part of the wave's energy to a dish or antenna which is usually located at the same site as the transmitter. Radar was secretly developed by several nations before and during World War II. The term RADAR was coined in 1940 by the United States Navy as an acronym for RAdio Detection And Ranging. The term radar has since entered English and other languages as the common noun radar, losing all capitalization. The modern uses of radar are highly diverse, including air traffic control, radar astronomy, air-defense systems, antimissile systems; marine radars to locate landmarks and other ships; aircraft anticollision systems; ocean surveillance systems, outer space surveillance and rendezvous systems; meteorological precipitation monitoring; altimetry and flight control systems; guided missile target locating systems; and ground-penetrating radar for geological observations. High tech radar systems are associated with digital signal processing and are capable of extracting useful information from very high noise levels.
U.S. National Library of Medicine
A system using beamed and reflected radio signals to and from an object in such a way that range, bearing, and other characteristics of the object may be determined.
