A radar apparatus includes: a plurality of receiving antennas disposed at regular spacings; two transmitting antennas which are positioned each at opposed ends of the receiving antennas, and a spacing of which away from the receiving antennas adjacent thereto is a natural number multiple of half a disposition spacing of the plurality of the receiving antennas; and a signal processor which, after the two transmitting antennas transmit electric waves in time divisions, and then one for each of the plurality of receiving antennas receives waves reflected from a target, subjects the obtained received signals to a digital beam forming process, in which case the signal processor, after subjecting the received signals to a fast Fourier transform process in a time direction, carries out a fast Fourier transform process in a space direction.
