Abstract: Based on the analyzing the plane wave spectrum-surface integral method,a new method using self-adaptive theory to part the sub_interval of multi-integral during the numerical calculation of the far directional pattern is presented in the paper. The result shows that the contradiction between the calculating speed and accuracy could be well balanced, and the calculating efficiency is greatly improved. ;;;
