Research on Accuracy and Error Analysis of Radar Water Level Measurement Technology in Songta Hydrological Station
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 0.999 4,indicating high correlation significance.The radar observation data can be officially used as hydrological data for this station.
