摘要

This paper describes an iteration-free numerical approach for the analysis of the monostatic Radar Cross Section of arbitrary scenarios. The proposed method is based on a combination of the Sparse Approximate Inverse of the near-field coupling matrix and the Multilevel Fast Multipole Algorithm, and allows to bypass the iterative solution process maintaining a good degree of accuracy.
