汽车测速系统中的相位基准信号及校正方法

Phase Datum and Correction Method for Vehicle Speed Survey System

介绍了基于多普勒雷达的汽车测速系统的原理 ,并对其中的相位基准信号进行了详细的分析 ,提出了对测量装置本身运动的校正方法 ,可有效地测量前方车辆的速度和距离 ,对雾天或夜间行车安全提供保障。

Introduces the fundamentals of the speed survey system based on DOPPLER RADAR,and the phase datum sign is analyzed in detail. A method of speed correction of the measure device is stated.So it can measure the speed and the distance between vehicles effectively and provide securiey to drive in foggy days or at night.
