| 摘 要： | 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174 d～2014年151 d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。

| Abstract: | 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 GPS-MR. The result is in good agreement with the measured snow depth data, and the correlation coefficient is greater than 0.97. |
