摘要(Abstract)：
随着GNSS研究与应用的不断深入,GNSS多径反射技术用于地表环境监测已成为一种新兴的遥感手段。针对目前国内对GNSS多径反射技术开展海平面变化探测研究较少的现状,该文通过分析信噪比值的变化特性,详细给出了基于信噪比观测值的GNSS多径反射技术探测海平面变化的基本原理。利用布设在美国华盛顿州Friday Harbor岸边的GPS连续运行跟踪站SC02观测数据反演了海平面变化,并与该站相距359m的Friday Harbor验潮站的监测数据进行了对比分析,误差均值为0.091m,相关系数为0.99。实验结果进一步验证了基于大地测量型GPS接收机用于海平面变化监测的有效性。
