摘要：
In this paper, several iterative methods with multilevel fast multipole algorithm (MLFMA) have been applied for solving large-scale scattering problems and compared with each other. The Bi-static RCS of four different targets, involving both open and closed objects, are calculated. Bi-CGSTAB, GMRES and Flexible GMRES (FGMRES) are employed in these simulations, and their performance are demonstrated. Based on these numerical results, suggestions about choosing the appropriate iterative method for different scattering targets are proposed, in order to minimize the solution time.
