What is radar in microwave?

Radar stands for radio detection and ranging. It is the use of reflected microwaves to determine vehicle speeds, track storms, or detect air traffic.

Most of the police speed radar is now up in the K and Ka band (~18 GHz and ~35GHz). These are all “microwaves” . Specific frequencies within those bands are chosen for the exact opposite you use in your microwave oven. For radar transmissions, we do not want the energy absorbed by water in the air.

Electromagnetic Waves ‘Microwaves are used in Radar’.

system or technique for detecting the position, movement, and nature of a remote object by means of radio waves reflected from its surface . Although most radar units use microwave frequencies, the principle of radar is not confined to any particular frequency range.
