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 or movement of objects.High-power radar, using large dish antennas, has been used to measure distances to the moon, other planets, asteroids, and artificial satellites.
