Radar warning receiver with position and velocity sensitive functions
First Claim
1. A police warning receiver comprising:
- a receiver section adapted to receive electromagnetic signals indicative of police activity;
an alert section responsive to the receiver section and adapted to provide an alert if a received electromagnetic signal correlates to a police signal; and
a position determining circuit generating a location signal;
wherein the alert section is further responsive to the location signal and adapted to alter or not provide the alert if the location signal correlates to a location of a rejectable signal.

Abstract
A GPS enabled radar detector (20) that aids in the management of unrelated or otherwise unimportant sources (16), permitting the detector to dynamically improve its handling of such sources based upon previously-stored geographically-referenced information on such sources. The detector includes technology (30, 32) for determining the location of the detector, and comparing this location to the locations of known stationary sources, to improve the handling of such detections. The detector may ignore detections received in an area known to contain a stationary source, or may only ignore specific frequencies or may handle frequencies differently based upon historic trends of spurious police radar signals at each frequency. A Global Positioning Satellite System (GPS) receiver (30, 32) is used to establish current physical coordinates. The detector maintains a list (50, 82) of the coordinates of the known stationary source “offenders” in nonvolatile memory. Each time a microwave or laser source is detected, it will compare its current coordinates to this list. Notification of the driver will take on a variety of forms depending on the stored information and current operating modes.
