The method of moments (MOM) in conjunction with the asymptotic waveform evaluation (AWE) technique is applied to predict the mono-static radar cross section (RCS) pattern of an arbitrarily shaped two-dimensional (2-D) perfect electric conductor (PEC) body.The electric field integral equation (EFIE) of a 2-D PEC body irradiated at a given direction by radar electromagnetic (EM) wave is solved using MOM to obtain the low order moments of the surface current on the PEC body.In the AWE technique,the surface current is obtained at any angle within the angular range expressed as a rational function,which is in turn used to calculate RCS of the 2-D PEC body.It was observed that AWE could result in considerable CPU time saving.
