该文介绍永定水文站HST-RD01SW非接触式雷达波测流系统组成、工作原理,并就其测量结果与水文缆道常规测量成果进行对照率定,结果表明,两者具有良好的相关关系。该雷达波测流系统测得的水面流速经率定后的水面流速关系推算的断面流量精度较高,适用于自动化水文遥测站流量监测,可为中小河流流量站仪器选型及先进技术的推广应用提供参考。
This paper introduces the composition and working principle of HST-RD01SW non-contact radar wave measuring system of Yongding Hydrological Station, and compares its measurement results with the conventional measurement results of hydrologic cableway. The results show that the two have a good correlation. The accuracy of the cross-section flow calculated from the relationship between the surface velocity measured by the radar wave flow measurement system and the determined surface water velocity is suitable for monitoring the flow of an automatic hydrological telemetering station and can be used for the selection of medium and small-sized river flow station instruments and the promotion of advanced technologies Application for reference.
