摘要
介绍了一种利用多普勒雷达检测车速、车距的系统方案。对系统主要参数的选择方法进行了论证。本系统可安装在汽车上 ,用于雾天或夜间监测前方车辆 ,并在车速、车距达到临界安全值时发出报警信号 ,以避免交通事故的发生 。
This article introduces a system scheme that use the DOPPLER-RADAR to check the speed of vehicle and the distances between vehicles.The system can be installed to the vehicle to monitor the forward vehicle in a foggy day or at night.It can give alarming signal when the speed of vehicle and the distance between vehicles reach the edge of security,so more traffic accidents can be avoided.
