Abstract:
In this paper, we propose a computational method for computing RCS of 3D conductor, by using piecewise surface impedance boundary conditions and forward backward iterative scheme. In our previous work, we have reported a numerical method combining Rytov's perturbation method and level set technique to construct a piecewise surface impedance, we showed that by using level set technique, we could model an arbitrarily shaped conductor by a piecewise distribution of low- and high-order SIBCs. The method proposed in this article postulates the use of local "buffer regions" to suppress spurious edge effects introduced by the abrupt termination of each SIBC and ensure stability of RCS computing.
