A fast efficient technique for solving monotonic RCS using the SVD method
In this paper, we apply multi-layer singular value decomposition (SVD) technology to the traditional characteristic basis function method (CBFM), then construct a series angle and polarization independent orthonormal characteristic basis functions (CBFs). By different linear combination of these orthonormal basic functions, we can get the surface current distributing of PEC object of any direction illuminating waves, and then we can obtain monotonic RCS. This article also combines Physics Optics (PO) method and dynamic storage binary tree technique, and it can reduce memory requirements and CPU-time. Numerical results show the correctness and effectiveness of this method.
