Abstract
Detecting continuous wave police radar includes receiving an input signal from a first antenna, the input signal comprising a continuous wave emission within at least one radar band; sweeping a composite local oscillator signal through a range of frequencies from a first frequency to a second frequency in a predetermined time period so that the composite local oscillator signal has a first chirp rate with a first chirp rate magnitude of between 0.15 MHz/μs and 3.5 MHz/μs or even higher; and mixing the input signal from the first antenna with the sweeping composite local oscillator signal to produce an output signal having an intermediate frequency. A next step can include determining that the input signal from the first antenna includes a police radar signal based on the output signal.
