中文摘要：

将提升类小波变换（lifting wavelet-like transform,LWLT）应用于矩量法（method of moment,MOM）快速求解电场积分方程（electric fieldintegral equation,EFIE）,对生成的稀疏化线性系统采用模基参数估计（model based parameter esti mation,MBPE）算法求解,可获得小波域的宽带解,结合小波逆变换,最终实现目标电磁散射特性的宽频分析。通过不同三维散射体的计算分析,验证了算法的正确性。与传统模基参数估计算法相比,所提算法在计算时间和内存耗费上均有很大改善。

英文摘要：

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.
