Abstract
In a radar device including: a transmission antenna group having a plurality of transmission antennas; a reception antenna group having a plurality of reception antennas; and transmission switchover means to transmit transmission waves in a way that sequentially switches over the transmission antennas of the transmission antenna group, the reception antenna group receiving reflected waves, reflected from a target, of transmission waves of the transmission antennas when sequentially transmitting the transmission waves, is made to function as a virtual sub-array corresponding to the transmission antennas. The target is thus detected by executing a space averaging process based on a relative position, to the reception antenna group, of each of the transmission antennas undergoing the transmission switchover with respect to the virtual correlation values corresponding to the plurality of virtual sub-arrays.
