摘要： Transmitting antennas and receiving antennas are arranged such that a plurality of virtual antennas have the same position in a time-division-multiplexed (TDM) frequency modulated continuous wave (FMCW) radar apparatus. At least three peculiar chirps, at least one of which is included in a chirp loop of each of waveform signals transmitted by the plurality of virtual antennas having the same position, are respectively positioned in consecutive time slots and have different periods. A Doppler frequency may be uniquely determined from phase difference values between the at least three peculiar chirps respectively positioned in consecutive time slots measured from FMCW radar signals received at the plurality of virtual antennas.
