A Novel Efficient Simplified Strategy for MLFMA

摘要：

　　To solve Iarge target RCS accurately and efficiently,based on CFIE (Combined Field Integral Equation),various factors influencing the memory,efficiency are analyzed in detail.Based on this analysis,a high-efficient and simple method used on solving large target RCS is proposed.By improving the comprehensive control and treatment on the gird,memory and precision of the algorithm,the aim that analyzing the electromagnetic scattering characteristic rapidly is realized under the condition of the effective resource.Numerical examples show that the simplified and efficient method is correct,and that other benefit such as improved computational efficiency and saved computational memory are obtained meanwhile the computational accuracy can be guaranteed.
