explsin the maening of radar?​

Answer 1

Answer:

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.

Answer 2

RADAR stands for Radio Detection and Ranging.

It uses frequently waves to find position, velocity etc of an object.
