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.

Display of radar signal detection alerts

A radar detector is operated to suppress nuisance radar alerts by identifying a first signal in radar band of interest, e.g., having a frequency that is a harmonic of a first nuisance local oscillator frequency leaked from a nearby radar detector and identifying a second signal having a frequency that is a harmonic of a second nuisance local oscillator frequency leaked from the radar detector where the first and second local oscillators are companion signals. A detector is also provided that suppresses nuisance radar alerts by detecting a first signal in a radar band, providing a first alert designating the detection of the first signal, determining that the first signal is a nuisance signal, providing a second alert designating that the first signal is a false alarm, and turning off the second alert after a predetermined period.

Systems and methods for discriminating signals in a multi-band detector

In a police radar detector, a sweep signal defines at least one first sweep signal and at least one second sweep signal with the at least one second sweep signal being seamlessly inserted into the first sweep signal so that the first sweep signal is interrupted during the second sweep signal and restored after completion of the second sweep signal so that the first sweep signal can be continued. The frequencies swept by the at least one second sweep signal are thus overswept. By assigning the frequencies swept during the at least one first sweep to the radar bands of interest and the frequencies swept during the at least one second sweep to the frequencies used in the POP mode of operation by police radar, the short bursts of energy used in the POP mode can be detected.
