The dimensions reducing technique combined with the Maehly approximation is applied to the Method of Moment (MoM) for analysis of the two-dimensional radar cross section (RCS) of the target. The Gauss-Green-Ostrogradsky (GGO) algorithm is utilized to transform the two-dimensional expression for the surface currents in both spatial and frequency domains to one dimension and its derivatives. This procedure avoids the solution of expansion coefficients in the two-dimensional expression and makes the accuracy adjustable by the order of derivatives. Compared with the two-dimensional Maehly approximation method, the proposed scheme can acquire RCS data efficiently with good accuracy and reduce procedural complexity. Finally, numerical results show that memory requirement and calculation time are about 1/6 and 1/3 of what are needed in the original method.
