The radar device comprises: a transmission unit that transmits, to an object, a transmission wave; a reception unit that receives a reflected wave, and generates a reception signal; and an object detection unit that acquires information relating to the object on the basis of the transmission signal and the reception signal. The object detection unit calculates, for each of a plurality of detection points within the same object: an azimuth angle φ indicating the azimuth of the detection point with respect to the radar device; and a velocity component V(φ) of the relative velocity A of the object along the azimuth. The object detection unit derives a relational expression for the azimuth angle φ and the velocity component V(φ), and derives a movement angle θ (=π/2−φ) indicating the movement direction of the object from the azimuth angle φ when V(φ)=0.
