Abstract

A radar apparatus includes a transmission-reception antenna unit including a plurality of transmission antennas and a plurality of reception antennas along a predetermined array direction, which form a virtual array in which a plurality of virtual reception antennas are arranged along the array direction. Based on virtual reception signals received by the virtual reception antennas, the radar apparatus detects an object that reflects transmission signals, calculates a transmission phase difference between the transmission antennas of the transmission signals transmitted by the transmission antennas, and calculates a reception phase difference between the reception antennas of reception signals received by the reception antennas. The radar apparatus calculates a transmission-reception phase difference that is a difference between the calculated transmission phase difference and the calculated reception phase difference, and determines that the detected object is a ghost, in response to the calculated transmission-reception phase difference being greater than a predetermined phase threshold.
