摘要
汽车雷达是减少交通事故的方法之一,在分析比较汽车防撞技术的基础之上,论述了毫米FMCW调频连续波雷达的原理,提出了基于DSP的主从处理器的设计方案,详细介绍信号处理流程。该雷达能及时检测前方障碍物的距离和相对速度,当超过门限值时能自动显示和报警,可有效降低交通事故发生率。
The automotive radar is one of the methods of reducing traffic accident.In this paper the technology about automotive collision avoidance is discussed,and the principle of millimeter wave radar based on FMCW is described .A new design with master - slave processor based on DSP is presented and processing flow of software system are introduced,The radar can detects the roadblock in front of it immediately and gives an alarm signal when the parameters exceed the set value ,and the traffic crash rate is reduced.
