X band K band

Ka band radar are radar waves between 33 . 4 GHz and 36.0 GHz . These are the most recent and the best radar band frequencies that law enforcement can operate on. There are as many as five different frequencies that these waves can operate on.

Ka band. The Ka band (pronounced as either “kay-ay band” or “ka band”) is a portion of the microwave part of the electromagnetic spectrum defined as frequencies in the range 26.5–40 gigahertz (GHz), i.e. wavelengths from slightly over one centimeter down to 7.5 millimeters .

K-band is a more common police band, yet it is also emitted from non-police sources such as vehicles equipped with driver’s assistance packages (Audi’s Collision Avoidance system, for example). Ka-band is the newest radar band in use, and it almost always indicates the presence of a police officer .
