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: 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: Provided is an improved estimation and identification device that estimates the position of a plurality of identification targets and identifies the plurality of identification targets. The estimation and identification device has a configuration comprising: a plurality of tracking devices that emit electromagnetic waves or sound waves and detect the position of an identification target on the basis of reflected electromagnetic waves or sound waves from the identification target holding a wireless transmission terminal; a plurality of wireless communications devices that wirelessly communicate with wireless communications terminals and receive identification information for the wireless communications terminals from the wireless communications terminals; and an analysis circuit that identifies the identification target and estimates the position of the identification target, on the basis of the results of the wireless communications results, the detected position of the identification target, and the identification information.
