From: GCIDE
- radar \ra"dar\ (r[=a]"d[aum]r), n. [acronym from RAdio Detection And Ranging.]
- 1. An electronic device designed to detect objects at a distance, and determine their distance from the device, by transmitting a pulse of radio waves and measuring the time required for the echo of the pulse to return to the emitting device; as, the radar showed a plane approaching rapidly. For more information of radar, see the article What is Radar?. [acronym] [PJC]
- 2. The method of detecting objects, finding their distance, or determining their speed, by use of a radar[1] device; as, modern radar can detect objects as small as raindrops. [PJC]
