Technology / Radar / K-Band: Police traffic radar has been assigned specific frequencies by federal communication commission (fcc). These frequencies are designated by the letters -s, x, k and ka and are referred to as bands. Older radar guns used s-band frequency, but this frequency is no longer in use. Ka band is the newest frequency used in police radars. Ka band is a wide band which allows police radar guns to operate on a multitude of frequencies. Ka-band: (frequency 33.4 -36.0 ghz: wavelength .344 inches)
