A radar detector is equipped with a positional tracking system, such as a global positioning satellite (GPS) system which can track the location of the vehicle in which the detector is located, and a processor enabling the detector to "learn" about the location of sources of false alarms. The learned information is stored in a "false alarm" database. When an alarm is detected, a comparison in made between the present location in the vehicle and stored information indicative of known locations at which false alarms have previously occurred. If the comparison is positive, the alarm is disabled, or the user is otherwise alerted to the fact that the alarm is likely to be false. If desired, a signal strength profile, frequency band of the energy causing the alarm, and/or time of day information can also be used to distinguish false from real alarms.
