Abstract:
1. A radar device including: an antenna for radiating beams in a plurality of directions and for receiving as reception waves the beams having been reflected by targets; a receiver for performing detection processing on the reception waves received by the antenna, to output received signals; a signal detector for extracting from the received signals outputted by the receiver quantities characterizing the reception waves; and a direction calculating unit for calculating a primary direction, being the direction of a target, from a combination of the characterizing quantities calculated by the signal detector based on the reception waves from at least two beams that partially overlap, among the beams radiated in the plurality of directions; the radar device characterized by a direction integrating unit for, when a plurality of primary directions calculated by the direction calculating unit is present, calculating an integrated direction, being the true target direction, from an area in which the density in a distribution of the plurality of primary directions is a predetermined value or greater, the integrated direction calculation being based on the primary directions belonging to the area.
