毫米波雷达常用调频连续波（frequency modulated continuous wave，FMCW）来测量目标的距离、速度等物理参数，但基于三角波调频连续波的雷达难以准确地完成多目标探测。因此，提出一种改进的FMCW波形及其对应的多目标匹配算法，这个复合型波形结合梯形波和快速锯齿波的特性，可以更准确地完成多目标的探测。仿真结果验证了该方法能准确剔除虚假目标，保留真实目标。
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.
