| Abstract: | In this paper,the principle of wavelet analysis theory is proposed.And a dividing stage GPS single epoch deformation signal de-noising method is presented based on multi-resolution probing to special noise embedded GPS single epoch deformation signal.In comparison with the conventional wavelet threshold value noise reduction method,the histogram of the residuals shows that this method can keep more deformation information. |
