Radar vs microwave

Noun. 1. microwave radar – measuring instrument in which the echo of a pulse of microwave radiation is used to detect and locate distant objects . radar, radio detection and ranging, radiolocation.

Radar uses radio waves which are electromagnetic waves and travel at a speed of 300,000,000 m/s.

Microwaves are electromagnetic waves of frequency range 1 GHz to 300 GHz. Since they are microwaves of smaller wavelengths, they can be transmitted as a beam signal in a particular direction. Also, microwaves do not bend around corners of any obstacle coming in their path . Hence, microwaves are used in radars.
