Abstract
Various targets are detected in a more accurate manner. Provision is made for a receiving antenna part that has a plurality of receiving antennas arranged in a horizontal direction with a part thereof being shifted in a vertical direction from the others, and has a plurality of combinations of the receiving antennas, of which each combination detects an azimuth in the horizontal direction and an azimuth in the vertical direction of a target; and detection means that detects the target a plurality of times while changing the combination of the receiving antennas. The detection accuracy of the target can be enhanced by making a comparison between at least two detection results obtained by the detection means.
