Abstract
A radar warning receiver is provided having a police radar signal band discrimination circuit which generates evaluation signals, the state of which indicates the voltage level relative a threshold voltage of a discriminator output as the local oscillator is swept through the radar bands. The times during which the evaluation signals are in one state or the other are utilized to identify in which band the received signal is operating (e.g., X-band or K-band).
