<p><P>PROBLEM TO BE SOLVED: To provide a radar device intruding object detector having high reliability, capable of avoiding misdetections by interferences among radar devices of a same radar frequency band concerning the radar device intruding object detector. <P>SOLUTION: The radar device intruding object detector includes an FMCW radar for detecting the relative speed and the distance between a target and own radar, by switching transmission and reception switches 22, 23 in reverse phase, and a means 40 for detecting radar detection receiving level, from at least a single reference reflection cross section reflector 32 placed at a fixed distance from the radar. By comparing the signal level and the threshold, when setting at a transmission and reception switching frequency where the reception level becomes null, so that interference disturbance is discriminated. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
