Abstract: A radar apparatus includes an antenna configured to radiate a first electromagnetic wave in a first radiation angle range including a first direction and radiates a second electromagnetic wave in a second radiation angle range including a second direction opposite to the first direction, and a circuit configured to detect a target in each of the first direction and the second direction on the basis of a first reflected signal of the first electromagnetic wave and a second reflected signal of the second electromagnetic wave, which are received by the antenna.

Abstract: A radar device includes a radar transmitting circuit that transmits radar signals from a transmission array antenna, and a radar receiving circuit that receives returning wave signals, where the radar signals have been reflected at a target, from a receiving array antenna. One of the transmitting array antenna and the receiving array antenna includes multiple first antennas of which phase centers are laid out along a first axis direction. The other of the transmitting array antenna and the receiving array antenna includes multiple second antennas of which phase centers are laid out at a second spacing along a second axis direction that is different from the first axis direction. The multiple first antennas include multiple antennas of which the phase centers are laid out at a first spacing, and multiple antennas of which the phase centers are laid out at a third spacing that is different from the first spacing.
