摘要
针对目前智能交通系统对于高性能车流量检测器的迫切需求,本文详细说明了基于双波束雷达的车流量检测系统的组成,分析了其检测原理,推导了信号处理过程,给出了仿真结果。理论分析和仿真结果表明:该检测系统不仅能够实现车辆存在与否、车道判别、车辆密度和时空占有率等各种交通参数的获取,还能实现车辆瞬时速度的测量。
A traffic detection system based on double beam radar is introduced for intelligent transportation system.On the basis of the general scheme for the system,the detection principles are analyzed and then signal processing and simulation are obtained.The detection system has a good performance in vehicle detection,such as lane discriminant,getting vehicle density and temporal occupancy,especially instantaneous velocity.
