Abstract
A police radar warning receiver includes a DSP circuit having a correlator and a peak detector to provide after each sweep of a swept local oscillator a dynamic threshold for that sweep as affected by all prior sweeps and against which information from that sweep is evaluated to determine whether to generate an alarm enable indicative of receipt of a police radar signal.
