It uses radio waves (usually in the microwave bandwidth) to detect things. Basically, since those radio waves are affected by the Doppler effect, you can have a computer do some math to determine the speed of whatever those waves reflected off of.

Every wave is affected by Doppler effect.
When a car rushes your way, it’s a tiny bit bluer, a little bit hotter, it’s drivers’ phone is operating on a slightly higher frequency and it sounds higher. According to you.

Well… also according to most physicists.
