1. A method, executed by a device having a position, of generating an alert to an incoming radar signal having a frequency and a signal strength, the method comprising the acts of:
- (a) detecting the incoming radar signal;
(b) determining the position of the device that detected the incoming radar signal; and
(c) generating an alert if the position of the device is not within a predetermined distance of a predetermined position.

Abstract
A radar detector for alerting an operator of a motor vehicle to an incoming police radar signal. This radar detector includes a microprocessor; a circuit coupled to the microprocessor for detecting the incoming police radar signal; and a global positioning system receiver coupled to the microprocessor. Upon detection of an incoming radar signal, the radar detector can utilize the position, velocity, and/or heading data from the global positioning system receiver to determine whether to generate an alert.
