Abstract:
1. A police radar detector comprising: an antenna for receiving incoming electromagnetic signals; a local oscillator for generating a local oscillator signal that is swept through ranges of frequencies to sweep portions of police radar bands in response to a sweep signal; a mixer coupled to said antenna and said local oscillator for mixing said incoming electromagnetic signals with said local oscillator signal to generate intermediate frequency signals; detector circuitry coupled to said mixer for detecting received electromagnetic signals within said police radar bands; and signal conditioning and control circuitry for generating said sweep signal to define at least one first sweep signal and at least one second sweep signal, said at least one second sweep signal being seamlessly inserted into said at least one first sweep signal so that said at least one first sweep signal is interrupted during said at least one second sweep signal and restored after completion of said at least one second sweep signal to continue said at least one first sweep signal.
