摘　　要：智能交通系统中,车流量检测雷达射频前端和数字信号处理器的信号处理算法是影响车流量检测雷达性能指标的两个重要方面。文中从车流量检测雷达实时性出发,简要介绍了基于DSP技术的车流量检测雷达的系统设计,同时给出车流量检测雷达DSP软件算法的完整设计思想,并具体解决了车流量检测雷达中车道识别这个关键问题,实现了车流量检测功能。最后还给出本课题组研制的车流量检测雷达的测试平台和测试性能指标,达到了实际使用的要求。In an Intelligent Traffic System （ ITS} the traffic flow detection radar is an important tool, which can carry out the intelligent traffic management. DSP signal processing algorithm can affect the traffic flow detection radar＇s performance specification. So this paper first presents the design idea of the software using the algorithm＇ s flexibility based on the real-time of traffic flow detection radar. And the method for identification of traffic lane is presented, which basically achieves the function of traffic： flow detection radar. Finally this paper presents the performance of our traffic flow detection radar and the hardware testing platform, which achieves the operation requirement.
