Radar is an acronym for "radio detection and ranging." A radar
system usually operates in the ultra-high-frequency (UHF) or
microwave part of the radio-frequency (RF) spectrum, and is used
to detect the position and/or movement of objects. Radar can
track storm systems, because precipitation reflects
electromagnetic fields at certain frequencies. Radar can also
render precise maps. Radar systems are widely used in
air-traffic control, aircraft navigation, and marine navigation.
