radar
n 1: measuring instrument in which the echo of a pulse of
microwave radiation is used to detect and locate distant
objects [synonym: {radar}, {microwave radar}, {radio detection
and ranging}, {radiolocation}]

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.
