基于多星GPS-IR的雪深反演分析
Analysis of Snow Depth Retrieval Based on Multiple Satellites GPS-IR
摘要
Abstract
It is an emerging study topic of using GPS SNR data to retrieval snow depth.Based on existing methods,a multi-star GPS-IR retrieval method is proposed.The method firstly evaluates the quality of single star retrieval results and removes the outburst value of snow depth,and then evaluates the multi-star GPS-IR retrieval results by power average.The theory and experiment show that the multi-star retrieval has higher precision and better reliability than single star does,and it can also well reflect the measured snow depth.关键词
