摘要
A radio wave incoming direction estimation apparatus according to an aspect of the present invention estimates an incoming direction of an incoming radio wave reaching an array antenna apparatus including a plurality of antennas. The radio wave incoming direction estimation apparatus includes a virtual current calculator, and an incoming direction estimator. The virtual current calculator calculates a virtual current at each antenna from a received current that is generated at each of the antennas by the incoming radio wave on the basis of data indicating a relationship between supplied power to each of the antennas and a current that is generated at each of the antennas by the supplied power. The incoming direction estimator estimates the incoming direction of the incoming radio wave on the basis of the virtual current at each of the antennas.
