Abstract
Provided is a radar detector for detecting and recognizing, as a control signal, a hand gesture or a motion of a user and transferring the same to a peripheral device. The radar detector utilizes position information of GPS or GLONASS by additionally mounting a GPS receiving unit to the radar detector so as to amend malfunctions of the radar detector in environments in which interference from undesired signals may be received, such as areas of heavy jamming, downtown areas where various signals are generated, etc., and to enable a user to arbitrarily add (or delete) a notification refusal area or a notification area. The radar detector is expected to contribute to safe driving by increasing control convenience of a driver and preventing traffic accidents.
