Abstract: Provided is a radar apparatus including: an estimation circuit; and a processing circuit. The estimation circuit outputs a plurality of pieces of data each including information in which a distance to a target and a direction to the target are estimated based on a reception signal including a reflected wave that is a radar signal reflected by the target. The processing circuit determines a range side lobe component in the target based on the estimated distance and the estimated direction of one or more pieces of data selected from the plurality of pieces of data.

Abstract: Performance of a radar apparatus including a plurality of transceiver ICs is improved. The radar apparatus includes: a plurality of integrated circuit, which, in operation, perform signal processing on a received signal; and a signal processing circuit, which, in operation, compensates for a deviation between the plurality of integrated circuits based on a difference between leak radio wave components received by receive antennas corresponding respectively to the plurality of integrated circuits.

Abstract: A radar apparatus includes signal processing circuitry, which, in operation, generates point cloud data for each frame based on a reflection wave signal resulting from a radar signal reflected by an object; extracting circuitry, which, in operation, extracts a first point cloud corresponding to a stationary object from the point cloud data; and superimposing circuitry, which, in operation, superimposes the point cloud data of a current frame and the first point cloud of a past frame.

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.
