摘要：
A police radar warning receiver includes a DSP circuit having a correlator, multiple array averager and a peak detector to provide after each sweep of a swept local oscillator respective dynamic thresholds associated with each averager array 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. The multiple averager arrays allow for different averaging or weighting ratios to maximize sensitivity of the receiver on the one hand and enhance response time on the other rather than trading off one for the other.
