In this paper,some traditional methods used for the filter of MBS sounding data,which are based on statistic analysis,are introduced and discussed firstly.By comparing and analyzing,we found the shortcomings of these traditional methods in practical applications.In order to get ideal filtering result,a new method,which is trend surface filter,is presented in this paper.The theory of the new method is depicted in detail.Some applications and analysis are also shown in the paper.Ideal filtering results achieved in actual applications show that the new method is credible.
