The present invention provides a radar detecting apparatus that is able to entirely prevent the generation of false alarms due to jamming waves.The radar detecting apparatus comprises a radar sensing portion and a GPS receiver displaying the current position of the automobile. While traveling, the radar detecting apparatus stores the locations, intensities, and so forth, of jamming waves, forms a jamming wave map, and creates a database of this information. The radar detecting apparatus refers to this database and suppresses the detection sensitivity of the radar sensing portion according to the intensity of the jamming waves when the automobile passes near jamming waves; this reduces false detection of radar waves. Also, the radar detecting apparatus calculates speed from the change in the position of the vehicle and prevents the output of an alarm by the radar detecting apparatus when the speed is at or below the speed limit of the currently traveled roadway.
