“…The frequency modulation continuous wave (FMCW) with chirp sequence, which is able to track multiple targets with more high‐accuracy range and velocity measurements, is the main form of the waveform in automotive radar [4, 5]. However, when using chirp sequence, velocity ambiguity may occur if the pulse repetition frequency (PRF) is lower than Doppler frequency of the target [6, 7].…”
