摘　　要：雷达水位测量技术的应用,可以有效避免因观测者视力差异、天气原因以及波浪壅水等因素造成的人工观测水位误差。研究基于松塔水文站2021年10月1日—11月1日的水位数据,验证雷达水位计在水位监测中的精度。结果表明,松塔水文站雷达水位计比测结果显示系统不确定度、随机不确定度和综合不确定度分别为-0.22 cm、2.67 cm和2.68 cm,系统误差0.94 cm。这些数据表明,雷达水位计的测量精度与人工观测相当。雷达水位计与人工观测水位相关系数R^(2)值为0.9994,相关显著性高,雷达观测资料可以作为松塔水文站正式的水文数据使用。The application of radar water level measurement technology can effectively avoid manual observation water level errors caused by differences in observer vision,weather conditions,and wave blockage.Based on the measured water level data from October 1 to November 1,2021 at Songta Hydrological Station,this study aims to verify the accuracy of radar water level gauges in water level monitoring.The results showed that the comparison of the radar water level gauge at Songta Hydrological Station showed that the system uncertainty,random uncertainty,and comprehensive uncertainty were-0.22 cm,2.67 cm,and 2.68 cm,respectively,with a system error of 0.94 cm.These data indicate that the measurement accuracy of the radar water level gauge is comparable to manual observation.The correlation coefficient R value between the radar water level gauge and the manually observed water level is 0.9994,indicating high correlation significance.The radar observation data can be officially used as hydrological data for this station.
