Radar is a system that uses electromagnetic waves to identify the
range, altitude, direction, or speed of both moving and fixed objects
such as aircraft, ships, motor vehicles, weather formations, and
terrain. The term RADAR was coined in 1941 as an acronym for radio
detection and ranging. The term has since entered the English language
as a standard word, radar, losing the capitalization. Radar was
originally called RDF (Radio Direction Finder) in the United Kingdom.
A radar system has a transmitter that emits either microwaves
or radio waves that are reflected by the target and detected by
a receiver, typically in the same location as the transmitter. Although
the signal returned is usually very weak, the signal can be amplified.
This enables radar to detect objects at ranges where other emissions,
such as sound or visible light, would be too weak to detect. Radar
is used in many contexts, including meteorological detection of
precipitation, measuring ocean surface waves, air traffic control,
police detection of speeding traffic, and by the military.
