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.

High probability of intercept radar detector

A device includes a radar signal detector that can determine a signal strength of a police radar signal and a direction of a source of the police radar signal. Additionally, the device includes a display in communication with the radar signal detector that provides a single display region having a visual appearance which varies based on both the direction and on the signal strength.

Combined display of radar signal direction and strength

An apparatus for a vehicle includes a radar detector configured to detect a police radar signal and a receiver configured to receive information about an image of an environment of the vehicle. A controller in communication with the radar detector and the receiver is configured to change at least one operating characteristic of the radar detector based on the received information.

Image analysis and radar detectors

A device includes a radar signal detector configured to detect a police radar signal and determine a frequency of the police radar signal and a display in communication with the radar signal detector and configured to provide a first display portion associated with a first range of frequencies. In particular, the display is further configured to provide a visual indicator associated with the police radar signal, the visual indicator having a first position within the first display portion which varies based on the frequency of the police radar signal and the visual indicator having a first visual appearance when the frequency is within a predetermined subset of the first range of frequencies and a second visual appearance when the frequency is outside the predetermined subset of the first range of frequencies.
