| 摘 要： | 将小波分析同矩量法相结合,首先,讨论了周期小波在电磁散射问题中的应用,并指出随着目标电尺寸的增大,该方法产生一个庞大而病态的阻抗矩阵,结果大量的计算机资源因此而耗费。其次,提出周期小波的两种改进算法,其中物理光学预处理算法改善了阻抗矩阵的病态性,降低了矩阵维数,提高了计算速度。

| Abstract: | This paper,first of all,discusses the application of periodic wavelet to electromagnetic scattering problems with the combination of wavelet analysis and moment method,and points out that with increase of target electrical size,the bulky and morbid impedance matrix will be generated;as a result,a large amount of computer resources will be wasted.Secondly,this paper puts forward two improved calculation methods of the periodic wavelet,among which pre-processing algorithm of physical optics will change the mo... |
