Abstract

A method and structure for solving a Doppler ambiguity problem in a time-division-multiplexed (TDM) frequency modulated continuous wave (FMCW) radar apparatus are proposed. In a frame of a waveform signal transmitted by one transmitting antenna in the TDM FMCW radar apparatus, at least three consecutive chirps having different periods are included for each chirp loop. A Doppler frequency may be determined from phase difference values between the three consecutive chirps measured from an FMCW radar signal received at a receiving antenna. The at least three consecutive chirps having different periods are configured to differ in at least one of an idle time between the chirps or a ramp time of the chirp.
