摘要
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.
