Millimeter-wave radar usually uses frequency modulated continuous wave(FMCW) to measure physical parameters such as distance and velocity of targets, but triangular waveform radar is difficult to accurately accomplish multi-target detection. As a result, an improved FMCW waveform and its corresponding multi-target matching algorithm are proposed in this paper, this composite waveform combines the characteristics of trapezoidal waveform and fast sawtooth waveform, through which multi-target detection can be finished more accurately. The simulation results verify that the method can accurately reject ghost targets and retain real targets.
