Abstract�� The moment method was used to calculate the RCS (radar cross section) of cell of great metal various body which has two-dimension periodic configuration��Then antenna array technology was used to compute the RCS of whole various body��The method could both ensure the precision of calculation and solve the difficult problem of large computation and coupling��Related mathematics formulas were deducted. On the condition of incidence of linear polarized plane wave, the example of calculation RCS of various metal pyramid was illustrated accordingly��The results are consistent with the conclusion which was obtained by using software HFSS(high frequency structure simulator),but the time taken to compute was much less than the time taken in the computation by using HFSS��The method is feasible to engineering.
Keywords�� radar cross section   electromagnetic scattering   moment method
