    • Four rows on the right 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 the remaining twelve rows form a reception channel group. Among the linear arrays forming the reception channel group, linear arrays of four rows in the center form reception channels CH5 to CH8 with each one row set as a channel unit. Linear arrays of eight rows on both sides (four rows on one side) form reception channels CH1 to CH4 with two rows set as a channel unit. A reception first array is formed by the reception channels CH5 to CH8. A reception second array is formed by the reception channels CH1 to CH8. 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 of the transmission array and a first side lobe of the transmission array is within a predetermined value.
