What bands of radar do police use?

K-band is the most widely used band of radar, not only by the police but also by other sources . K-band is being emitted by automatic doors, security systems, and cars with collision avoidance and lane departure warning. The third band of police radar is called Ka-band.

Radar systems transmit electromagnetic, or radio, waves. Most objects reflect radio waves, which can be detected by the radar system. The frequency of the radio waves used depends on the radar application. … 16.1 Radar Frequency Bands.

Police radar operates on 24.15 GHz .” “Radar Applications by Frequency.” Encyclopedia Britannica.

Police radar transmits radio waves on a specific frequency, and the three frequency bands currently in use (in North America) are X-band, K-band, and Ka-band . X-band is nearly obsolete, yet maybe encountered near automatic doors or in rural areas with small police departments.
