Abstract：An efficient numerical approach is presented to analyze the electromagnetic scattering characteristics from conducting targets based on the Characteristic Basis Function Method (CBFM). Combined with the Improved Fast Dipole Method (IFDM), the matrix-vector product is transformed into an aggregation- translation-disaggregation form, which in turn accelerates the matrix-vector multiplication procedure in the generation of Secondary level Characteristic Basis Function (SCBF) and construction of reduced matrix. The computational time and memory consumption are reduced significantly compared with the traditional method of Fast Dipole Method-Characteristic Basis Function Method (FDM-CBFM) under the equivalent precision. Numerical results demonstrate that the proposed method is accurate and efficient.
