By this arrangement, the first stage estimation direction D1(N) is suddenly changed on a large scale by an influence of the multipath, thereby when the estimated movement distance B becomes large, the weighting factor W becomes to a small value. By means of performing a weighted average of multiple frequencies of the first stage estimation direction D1 with the use of this weighting factor W to determined the second stage estimation direction D2(N), influence of the multipath can be suppressed, and the accurate direction finding becomes attainable.
