Each antenna system processor performs coherent integration on a prescribed number of correlation values between a reception signal and a transmission code. A correlation matrix generator generates a correlation matrix on the basis of coherent integration values. A distance estimator estimates a distance to a target. A direction vector storage is stored with direction vectors each of which includes an azimuth component with respect to a target and an elevation angle component of a line connecting a transmission antenna and the target in which a prescribed direction is used as a reference. An incoming direction estimator estimates a signal incoming direction from the target using the correlation matrix and the direction vectors in which the elevation angle component range is restricted on the basis of the distance to the target.
