There always are some breakpoints and bifurcation points in measured data of target radiation and scattering characteristics, which have a great impact on the data effectiveness. While among the existed pre-processing methods, the original bifurcation point becomes more prominent or makes a part of a signal. These pre-processing methods will have an effect on subsequent extraction and recognition for features. A data pre-processing method based on multi-threshold which effectively removes the numerical singularity and enhances the signal to noise ratio without changing the original signal is given in this paper.
