According to the present invention, a compensation-vector calculating unit 26 is provided which uses a radiation pattern gn (θm) of each element antenna 2-n (n=1, 2, ···, N) in a state where a mutual connection is established among element antennas 2-1 to 2-N, and a radiation pattern E (θm) of a phased array antenna 1 in a state where a mutual connection is not established among the element antennas 2-1 to 2-N, and which calculates a compensation vector wn for compensating the influence of the mutual connection on the element antenna 2-n. A phase shifter control device 27 uses the compensation vector wn calculated by the compensation-vector calculating unit 26, sets excitation phases φ1 to φN of the element antennas 2-1 to 2-N, and indicates the excitation phases φ1 to φN to phase shifters 3-1 to 3-N. |
