In the UK only to radar frequencies used, K band and Ku band (in a very limited way). Coverage of other frequencies other than these bands will cause the detector to false alarm, devices such as traffic lights supermarket doors, mobile phones and transmitters often operate on the X band.

Many police radar guns use this measure to calculate the speed of a vehicle and they can operate on X bands, K bands, or Ka bands, although Ka bands are the most widely used since they are the most current and accurate technologically.

Most radars, in practice, operate between 400 MHz to 36 GHz ; however, there are some notable exceptions. The optical and radio portions of the electromagnetic spectrum occupy positions coincidental with two important transparent bands in the Earth’s atmosphere and ionosphere.

This permits target detection at distances from about 500 to 2,000 nautical miles (900 to 3,700 km) . Thus, an HF over-the-horizon (OTH) radar can detect aircraft at distances up to 10 times that of a ground-based microwave air-surveillance radar, whose range is limited by the curvature of the Earth.
Read moreWhat can a radar detect?
Radar (radio detection and ranging) is a detection system that uses radio waves to determine the distance (ranging), angle, or relative velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain .
Read moreCan radar detect humans?
Doppler radar cannot detect humans who are stationary or walking across the radar’s field of view . The radar can only detect the motion components that are directed towards to or away from the radar.
