GNSS-R水位监测研究进展与其在我国水利行业应用展望OA北大核心
Research progress of GNSS-R water level monitoring and its application prospect in China's water conservancy industry
水位监测在水文学、水利工程、灾害防治等领域都具有非常重要的意义.传统的水位监测方法存在成本高、覆盖范围小等缺点,GNSS不仅具有导航、定位及授时的功能,还可以利用其反射信号获取反射面的特性信息并将其称为全球卫星导航系统反射测量(Global Navigation Satellite System-Reflectometry,GNSS-R).近年来,GNSS-R技术以低成本、全天候、高时空分辨率等优势为水位监测提供了 一种新方法.本文对GNSS-R水位监测的研究现状、不同方法的影响因素以及当前应用过程中存在的问题进行了总结归纳提出了下一步的发展趋势,最后对其在我国水利行业的应用进行了展望.
Water level monitoring is crucial for the fields of hydrology,hydraulic engineering,and disaster prevention and control.Traditional methods of monitoring water levels have several drawbacks,including high costs and limited coverage.The Global Navigation Satellite System(GNSS)serves multifaceted functions,including navigation,positioning,and timing.Additionally,it can harness its reflection signal to extract characteristic information from the reflecting surface,a technique known as GNSS reflection signal remote sensing(GNSS-R).In recent years,GNSS-R technology has emerged as a novel approach for water level monitoring,offering advantages such as cost-effectiveness,all-weather operability,and high temporal and spatial resolution.This paper provides a comprehensive review of the current state of research in GNSS-R water level monitoring.It discusses the influencing factors of different methodologies and identifies challenges encountered in the application process.Furthermore,it proposes future development trends and anticipates its potential application in China's water conservancy industry.
