摘要
From the perspective of continuous variation of deformation field, a method by using multi-kernel function to filtering and analysis is proposed with 4 observations (1999~2007) in the GPS network of North China, the results show as follows. Firstly, mathematical analysis of vertical motion field can be obtained. Secondly, different levels of filtering and information separation of vertical deformation field can be realized. Thirdly, if the space density of mobile stations,quantity and time length of repetition measurement can reach a certain level, reliable deformation information can be achieved. Finally, a practical example and preliminary analysis results with GNSS mobile observations in North China were given.
