The method of moments (MoM) in conjunction with the best uniform rational approximation is applied to predict monostatic radar cross section (RCS) pattern from a few pattern value calculations. Numerical results for three-dimensional arbitrarily shaped perfectly electric conductor objects are considered. Good agreement between the proposed technique and the exact solution is observed. Compared with the asymptotic waveform evaluation (AWE) technique, the proposed technique is accurate in much broader angular domains.
