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 one combination of different numbers of multiplexing by the code sequences.

Abstract: An object detection apparatus in a vehicle is provided. The object detection apparatus includes one or more sensors configured to detect at least one object located on at least three rows of seats in the vehicle, the one or more sensors being positioned on a ceiling of the vehicle. The object detection apparatus further includes a circuit configured to determine whether or not the at least one object detected is a living-object. A number of the one or more sensors is less than a number of the at least three rows of seats.

Abstract: False detection of a ghost is prevented. A radar apparatus includes: transmission circuitry, which, in operation, transmits a radar signal; main reflective object detection circuitry, which, in operation, detects a main reflective object in a detection area using a reflected wave of the radar signal; in-area determination circuitry, which, in operation, determines a main area where a ghost caused by a reflective object outside the detection area and the main reflective object is located, the main area being inside the detection area; and auxiliary reflective object detection circuitry, which, in operation, detects a position of an auxiliary reflective object in the main area using a reception signal of the reflected wave of the radar signal, the auxiliary reflective object being located farther than the main reflective object on an extension of a line connecting the radar apparatus and the main reflective object.

Abstract: A tracking apparatus includes a processor circuit that derives a center of gravity of point group data obtained from reflected waves reflected by a target reflecting radar waves, that finds a position in horizontal direction of the center of gravity, that determines a posture of the target from a distribution in at least either vertical or horizontal direction of the point group data, that, in a case where the position found and the posture determined satisfy predetermined conditions, analyzes a Doppler distribution of the target, and that assess a state of the target.
