摘　　要：针对微波车流量检测雷达的要求,设计并实现了基于DSP芯片TMS320VC5502的数字信号处理机,对车流量检测雷达系统接收到的回波信号进行实时采样和分析计算出道路车流量。实验表明:该系统稳定可靠,满足智能交通系统对车流量检测器的要求。To meet the requirements of traffic flow detector, designed and implemented the digital signal processor based on DSP TMS320VC5502. The processor deal with the echo signal received from microwave flow detection radar system, and computes the road traffic flow in real - time. Experiments show that ： the system is stable, reliable, and meets the requirements of traffic flow detector in intelligent transport system.
