Abstract：In this paper, the numerical method of combining surface parametric quadratic modeling with singularity orders reducing in moment method is analyzed. The objects are modeled by parametric quadratic surface. The singularity order of the integral is reduced from O(1/R2) to O(1/R). Compared with other methods, this method simplifies the complexity of self-impedance elements calculating and increases its calculating stability and accuracy. It is applied to calculating RCS of some objects. Good agreement with the results from some other methods is found.
