Abstract
Numerical methods for the derivation of diffraction coefficients are described. Scattered fields from finite bodies with scattering centers of interest are calculated by the moment method and are expressed in terms of unknown diffraction coefficients. The diffraction coefficients are then extracted by solving equations. The examples investigated show the feasibility of this method
