摘要

用于机车测速的多普勒雷达传感器的天线波束方向与地面实际夹角随着机车的震动会发生改变

导致雷达测速传感器测量的速度值与机车实际速度存在一定偏差

双天线雷达测速传感器采用双天线结构

利用两片天线的角度关系及两片天线所接收信号的能量大小自动校正天线波束与地面夹角。通过Matlab分析数据与实际测试

角度修正后的雷达传感器系统速度测量值更接近机车真实速度。

Abstract

The actual angle included between antenna beam direction of radar speed sensor used for measuring speed of the locomotive and horizontal will change as the locomotive vibrations

which lead to a certain deviation between the speed value of radar sensor measuring and the actual speed of the locomotive. In order to improve the accuracy of the speed measurement values

radar speed sensor with a dual antenna can automatically correct the angle between antenna beam and horizontal. By Matlab data analysis and practical test

velocity measurement value of the radar sensor system with angle correction is closer to real locomotive speed.
