<p>PURPOSE:To eliminate a seek lack and a target which does not exist in an expected relative distance, and to detect only a true target by scanning a search scene two times at a prescribed time interval, and taking a correlation of each value. CONSTITUTION:In a coordinate correcting circuit, a converted area A is obtained by correcting a coordinate of a target detected by a scan of the first time. In a scan correlating circuit, in a target SA detected by a scan of the second time after a prescribed time has passed from the scan of the first time, only that which is contained in the converted area A is recognized, and it is decided to be a true target SP.</p> |
