Abstract
A detector for detecting continuous wave police radar that includes an antenna configured to receive an input signal, a diplexer in communication with the antenna to separate the input signal into a high-band signal and a low-band signal, a local oscillator configured to sweep through a range of frequencies to produce F, and a frequency multiplier to generate a first mixing signal that is an integer multiple of F. The detector also includes a high-band intermediate-frequency signal and a low-band intermediate-frequency signal with a switch configured to select one of them as an output intermediate-frequency signal. A second-stage mixes the output intermediate-frequency signal with Fto generate an output signal, and a determination is made whether the input signal includes a police radar signal.
