PROBLEM TO BE SOLVED: To separate signals of arbitrary incoming signals. SOLUTION: An adaptive array antenna system comprises: an array antenna 106 including a plurality of antenna elements 101 for receiving a plurality of incoming signals; a direction estimating means 107 for estimating a direction of arrival for each incoming signal; a power estimating means 108 for estimating power for each incoming signal; an acquisition means 109 for acquiring the plurality of reception signals received by the array antenna by turning a beam toward the direction of arrival, estimated by the direction estimating means 107, for an incoming signal with maximum power in the power estimated by the power estimating means 108; and a separation means 111 for separating the plurality of incoming signals by applying an eigenvector beam spacing method to the plurality of reception signals.
