Signal Analysis and Measuring Method for Hump Yard Speed Measuring Radar

测速雷达是驼峰场车辆溜放控制系统中的重要测量设备。本文简述目前在驼峰场广泛应用的多普勒雷达测速原理，分析了雷达信号和噪声，提出一种基于频谱分析测速的方法。

Speed-measuring radar is a very important piece of equipment in the cuturolling control system on hump yards. This paper briefes on Doppler radar and underlying prlnciple widely used in measuring cut speed at present; analyses the radar signal and noise and advances a new method based on signal frequency spectrum analysis.
