| 摘 要： | 在雷达观测基线受限且波束不扫描的条件下，近程小扇区内多个独立运动目标的分辨、定位、跟踪和参数估计等，是雷达探测技术领域中亟待解决的理论问题，更是汽车防撞雷达等应用中需要突破的技术难点，线性调频连续波（LFMCW）信号形式可以实现近程、无盲区、高分辨、高精度探测和距离信息获取，能够有效解决近程小扇区雷达面临的问题．分析了汽车防撞雷达中近程小扇区雷达的原理，对汽车防撞雷达的需求和体制进行了阐述；提出了汽车防撞雷达的参数选择和系统设计，并分析了其工作原理．

| Abstract: | Under limited observation baseline and without scanning beam,the problems of distinguishing multiple independent moving targets,parameters estimation,target tracking in the short-range narrow field of view(FOV),are not only urgent to solve theory of radar detection,but also cause dificulties to the application of anticollision radar.The linear frequency-modulated continuous wave(LFMCW)takes advantages of the simple structure,none range blind zone and high resolution in short range of LFMCW radar,and realize... |
