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.

Microwaves are used for radars because they can pass through anything.
They lie between infrared and radio waves and so cover a huge range of frequencies.
Radars are designed to track very fast moving objects like planes, rockets and bombs.
The wide range of frequency enables us to detect more aircraft and projectiles.
They travel very fast and can reach any point of the battleground in some time.
