Abstract

A radar detector and location unit includes at least three sensors configured to detect a radar signal, at least three sensors being aligned in a non liner arrangement; a position receiver configured to determine a position of the radar detector; a data storage device configured to store data related to a location of a known series of radar emissions sites; a processor connected to the at least three sensors, the position receiver and the data storage device. The processor is configured to determine the location of the radar emission based on a coordination between the at least three sensors and the position of the radar detector. The processor is further configured to compare the location of the radar emission with locations in a known series of radar emissions sites.

Claims

1. A radar detector and location unit comprising:

at least three sensors configured to detect a radar signal, the at least three sensors being aligned in a non linear arrangement;

a position receiver configured to determine a position of the radar detector;

a data storage device configured to store data related to a location of a known series of radar emissions sites;

a processor connected to the at least three sensors, the position receiver and the data storage device;

wherein the processor is configured to determine the location of the radar emission based on a coordination between the at least three sensors and the position of the radar detector; and

wherein the processor is further configured to compare the location of the radar emission with locations in the know series of radar emissions sites.

2. The radar detector of claim 1 further comprising:

a map interface configured to display the location of the radar emission on the map.

3. A method of determining a location of a radar emission at a radar detector, comprising:

receiving a signal from the radar emission at at least three sensors configured to detect a radar signal;

receiving a signal indicative of the location of the radar detector;

determining the location of the radar emission based on the received signals from the sensors and the received signal indicative of location;

comparing the determined location with a list of known radar source locations; and

ignoring the radar emission if the determined location matches an entry in the list of known radar source locations.

4. The method of claim 3 further comprising;

displaying the location of the radar emission on a map.

5. The method of claim 4 further comprising:

highlighting on the map the location of an unidentified radar emission.
