雷达测流仪比测分析

摘要

S3⁃SVRⅡ model of wireless remote control digital measurement system of radar is a new kind of non⁃contact river flow test system. This paper analyzed the test error of radar for measuring water flow velocity and discharge. With the rotor flow meter measurement, radar measurement system error can be controlled within ±1%, random uncertainty is beyond the"standard" requirement, but radar measurement precision meets the requirements of small and medium⁃sized rivers.%S3－SVRⅡ型无线遥控雷达波数字化测流系统是一种新型的非接触式河道流量测验系统，分析了雷达施测水面流速和流量的测验误差，并与转子流速仪进行了比测。结果表明：雷达测流系统误差可以控制在±1％以内，随机不确定度超出了规范要求，但雷达测流精度满足中小河流水文监测要求。
