| Abstract: | Based on the method of moments, the two dimensional electrically large conducting object is divided into several small regions by employing spatial decomposition technique. Considering the coupling effect between sub regions, the surface currents are calculated with the progressive iterative numerical method, and the wide band RCS is obtained by asymptotic waveform evaluation technique. The numerical results presented in this paper are in good agreement with that achieved by the method of moments (MoM), and the proposed scheme exceeds considerably MoM in the computational efficiency. |
