利用GPS的SNR观测值进行雪深监测研究

Snow Depth Detection with GPS SNR Observations

在分析多路径与信噪比关系的基础上,给出基于SNR观测值的GPS-MR技术探测雪深的基本原理。利用板块监测PBO网P360站2013年174d^2014年151d的GPS实测数据进行算例分析,其结果与实测雪深数据吻合较好,相关系数大于0.97。

Based on the relationship between multi-path and SNR,in this paper we give the basic principle of GPS-MR based SNR to detect snow depth.Data in P360 are used to verify the validity of GPSMR.The result is in good agreement with the measured snow depth data,and the correlation coefficient is greater than 0.97.
