Abstract
Four rows on one side of linear arrays arranged at equal intervals in the vertical direction and arranged at a predetermined interval in the horizontal direction form transmission channels and remaining twelve rows form a reception channel group. Among the remaining twelve rows, linear arrays of four rows in the center form a reception-first-array with each row set as a channel unit. Linear arrays of eight rows on both sides form a reception-second-array with two rows set as a channel unit. In wide-angle-middle-detection-processing, signals are combined using the reception-first-array. In long-detection-processing, signals are combined using the reception-second-array. Second null of a radiation pattern by a transmission array and first null of the reception-second-array are matched. The first null of the transmission array is filled such that a gain difference between the first null and a first side lobe of the transmission array is within a predetermined value.
