Abstract
A transmission antenna unit includes a plurality of transmission antennas, a reception antenna unit, and a processor. The plurality of transmission antennas that are arranged in a row along a predetermined array direction. The reception antenna unit includes a plurality of reception antennas that are arranged in a row along the array direction. The plurality of transmission antennas and the plurality of reception antennas form a virtual array in which a plurality of virtual reception antennas are arranged in a row along the array direction. The processor corrects a plurality of virtual reception signals by multiplying a virtual reception signal matrix by an inverse matrix of a reception mutual coupling matrix and an inverse matrix of a transmission mutual coupling matrix.
