ABSTRACT:
A radar apparatus is provided which includes a plurality of antennas arranged at unequally spaced intervals in a single row, the plurality of antennas configured to transmit a radio wave as transmitting antennas during continued multiple periods, and receive a reflected radio wave as receiving antennas during the continued multiple periods. A plurality of transceivers are included for transmitting a radio wave from the transmitting antennas and receiving received signals from the receiving antennas, said received signals representing the reflected wave received at the receiving antennas. A signal processing unit is included for selecting a transceiver which transmits a radio wave during each of the continue multiple periods, selecting transceivers which receive the received signals from the receiving antennas during each of the continued multiple periods, and perform digital beam forming with a first receiving signal channel group and a second receiving signal channel group.
