摘　　要：针对传统的线性调频连续波(LFMCW)雷达在进行运动多目标配对的局限性,提出结合变周期LFMCW作为发射信号波形,采用质心凝聚处理进行多目标配对的新方法,有效提高了处理算法的实时性,合理设置凝聚中心宽度阈值,可实现目标的准确配对和距离速度去耦合,测试结果显示:配对误差均控制在5%以内。Aimed at the limitations of the conventional linear frequency modulation continuous wave（LFMC） radar during moving multi-target pairs.Combining with a variable cycle as the transmission signal waveform LFMCW,using a new way of cohesive centric processing of multi-target pairing to achieve goals exactly matching and distance speed to the coupling,which effectively improves processing algorithms in real time.Reasonably set the width of the threshold pool centers can achieve the exact target matching and distance speed to coupling.The test results show that matching error is less than 5 %.
