Motor vehicle police radar detector for detecting multiple radar sources
First Claim
1. A motor vehicle police radar signal detector for alerting an operator of a motor vehicle to incoming radar signals from more than one radar signal source, said radar signal detector comprising:
- receiver means for receiving incoming radar signals;
detector means coupled to said receiver means for detecting said incoming radar signals;
signal processing means coupled to said detector means for identifying detected radar signals, storing identification signals representative of detected radar signals, and determining the number of stored identification signals which correspond to incoming radar signals generated by different radar signal sources; and
alarm means for alerting an operator of a motor vehicle using said radar signal detector of the number of different radar signal sources which are directing radar signals toward said motor vehicle.

Abstract
A police radar signal detector detects and monitors radar signals from up to nine (9) radar sources until a detected radar signal has not been redetected for a given number of detector operations, or spectrum sweeps, or until a detected signal has been displaced by a higher priority radar signal. In the police radar signal detector of the present invention, a user of the detector is advised not only of the presence of detected radar signals, the frequency band of detected radar signals and the relative field strength of the signals but also of the number of different radar signal sources which are transmitting signals toward the user'"'"'s motor vehicle. The information provided to the user for the frequency band of detected radar signals and the relative field strength of the signals is for the highest priority radar signal detected if more than one signal has been detected and is being monitored by the detector of the present invention. In addition, the directions of radar sources are determined and the user of the detector is advised of the direction or directions, front, side and rear, of origin of radar sources transmitting signals toward the user'"'"'s motor vehicle. If sources are oriented at more than one direction relative to the user'"'"'s motor vehicle, an indicator is illuminated to advise the user of all the directions of origin with the indicator for the direction of origin of the highest priority signal being flashed to so advise the user of the detector. Further, since multiple radar signals can be detected, each time a new radar signal is detected, a distinctive memo alarm is activated to alert the user to the presence of a new radar signal source.
