摘要：
The lifting wavelet-like transform (LWLT) is applied to the method of moments (MOM) for fast solution of electric field integral equations (EFIE), and a sparse linear system is obtained, which is solved by the model based parameter estimation (MBPE) to complete the solution over a wide band in wavelet-domain. Finally, the wide band scattering analysis is finished with the help of inverse wavelet transform. The proposed algorithm is validated by considering numerical examples of different shaped three-dimensional objects. Compared with the traditional MBPE method, the presented algorithm can save much CPU time with low memory consumed.
