Abstract
A police radar detector detects police radar signals in the X, K and wide Ka police radar bands and rejects interfering Ka band signals that are a higher harmonic of a nuisance source having a fundamental frequency adjacent to the X police radar bands. Each of the three police radar bands is separately swept in a first mixer stage with the resulting IF signal concurrently demodulated in two IF circuits. The first IF circuit detects signals that were received in the X, K and outer portions of the wide Ka band during respective sweeps. The second IF circuit detects nuisance signals adjacent to the X and K bands, and the inner portion of the wide Ka band during respective sweeps.
