PROBLEM TO BE SOLVED: To solve such problems that, in a conventional radar apparatus, the position of an own station is searched by radio waves in a monostatic radar apparatus whose transmission-reception is performed by the same antenna and that direct waves and reflected waves must be received respectively by separate antennas in order to receive faint reflected waves from a target in the case of a bistatic radar apparatus using radio waves whose transmission factor is unclear. SOLUTION: The direction of the direct waves and that of the reflected waves are estimated by using an ultraresolution algorithm such as MUSIC or the like for a received signal. After that, the direct waves and the reflected waves are separated and extracted from the received signal. Even when transmitted waves are used as the direct waves and even when the direct waves and the reflected waves are received by the same antenna, the distance and the direction of the target can be found, and the position of the own station can not be searched.
