Abstract
A system for detecting fake information about a vehicle location may include a radio signal receiver configured to receive a radio signal from a communication system; a message receiver configured to receive the radio signal to generate a message and determine the message to generate information about a location of the communication system; a radio signal incident angle calculator configured to generate a radio signal incident angle; an azimuth calculator configured to generate a location information azimuth angle by use of the information about locations of the communication system and a receiving vehicle, and a fake vehicle generated by the communication system; and a location information fake detector configured to determine whether location information of the fake vehicle is faked by use of a difference value between an angle corresponding to a reference axis of the location information azimuth angle and the location information azimuth angle.
