1. A radar apparatus, comprising:
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 are 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,
wherein the auxiliary reflective object is different from the main reflecting object, and is located farther than the main reflective object on an extension of a line connecting the radar apparatus and the main reflective object.
