PROBLEM TO BE SOLVED: To achieve a target detection apparatus which can perform more accurate scan correlation processing.;SOLUTION: A correlation processing unit 6 of the target detection apparatus 100 performs scan correlation processing on echo data in the polar coordinate system stored in a sweep memory 2 and scan correlation processed stored data in the previous scan stored in the polar coordinate system in a read memory 70B, wherein an address determination unit 5, using antenna rotation information from an antenna rotation information acquisition unit 3, position information from a position detection unit 4, and the compass direction of the head, sets a read address so that the coordinate system of the echo data from the sweep memory 2 and that of the scan correlation processed stored data from the read memory 70B match and gives it to the read memory 70B. A write memory 70A stores the scan correlation processed stored data from the correlation processing unit 6 in accordance with a write address set in the coordinate system of the standard timing of the present scan by the address determination unit 5.;COPYRIGHT: (C)2011,JPO&INPIT
