Abstract: One of a transmitting array antenna and a receiving array antenna includes a first antenna group and a second antenna group. The first antenna group includes one or more first antenna elements of which the phase centers of the antenna elements are laid out at each first layout spacing following a first axis direction, and a shared antenna element. The second antenna group includes a plurality of second antenna elements and the one shared antenna element, and the phase centers of the antenna elements are laid out in two columns at each second layout spacing following a second axis direction that is different from the first axis direction. The phase centers of the antenna elements included in each of the two columns differ from each other regarding position in the second axis direction.

Abstract: A radar apparatus includes a plurality of transmit antennas that transmits a plurality of transmission signals using a multiplexing transmission, and a transmission circuit that applies phase rotation amounts corresponding to combinations of Doppler shift amounts and code sequences to the plurality of transmission signals. Each of the plurality of transmission signals is assigned a different combination among the combinations. The combinations include at least two combinations of a same number of multiplexing by the code sequences.

Abstract: A radar apparatus includes a radar transmission circuit that transmits a radar signal from a transmission array antenna, and a radar reception circuit that receives, from a reception array antenna, a reflected wave signal that is the radar signal reflected at a target. One of the transmission array antenna and the reception array antenna includes a first antenna element group having m antenna elements arranged at a first interval Dt along a first axis direction, wherein m is an integer of 2 or larger. The other one of the transmission array antenna and the reception array antenna includes a second antenna element group having n antenna elements arranged at a second interval Dr along the first axis direction, wherein n is an integer of 4 or larger. The second interval Dr includes several different intervals.

Abstract: This receiving array antenna includes multiple receiving antenna rows, and each of the receiving antenna rows contains a first number of antennas; of the first number of antennas contained in the receiving antenna rows, mutually adjacent antennas are arranged separated by a first interval in a first axis direction and by a second interval in a second axis direction. The transmitting array antenna includes multiple transmitting antenna rows arranged in the second axis direction at an interval that is the first number times the second interval, each of the transmitting antenna rows contains multiple antennas, and the multiple antennas contained in the transmitting antenna rows are arranged in the same position in the second axis direction and in different positions in the first axis direction. The antennas contained in the transmitting antenna rows adjacent in the second axis direction are arranged in different positions in the first axis direction.
