MONO-STATIC RCS COMPUTATION WITH A BLOCK GMRES ITERATIVE SOLVER

Abstract

We present a new method of computing mono-static radar cross sections using a preconditioned Block GMRES iterative algorithm. The convergence properties of this algorithm are analyzed using RCS error, equation residual error and solution error. It is found that this method is nearly an order of magnitude faster than direct methods (LINPACK) for realistic method of moment problems.
