- Abstract:
- GNSS observation data help us to reveal the crustal strain field,but the data have some shortcomings to reflect all kinds of strain information completely and appropriately.On the point of continuous variation,and on the foundation of the horizontal-motion field of ITRF reference frame,we obtain the analytic expression of horizontal-motion field by means of multi-kernel function.Further,the strain field result is given by using spherical non-deviation expression,and space filtering is carried on by means of multi-kernel function.Finally,we give a practical example of strain calculation using this method.Both theoretical and example analysis suggest that the method we proposed has characteristics as follows:① It is suitable for the strain field comprehensive and objective description of every space scale; ② Different frequency spectrum and its strain information can be extracted according to different requirements and data; ③ Precision of strain parameters can be evaluated rigorously; ④ Further analysis and calculation can be done on the foundation of analytic expression.
