摘要

本文提出了一种有效的一维介质随机粗糙表面轮廓重建算法。首先通过传统的曲面积分方程求解直接问题,得到合成散射场数据。然后用迭代法求解同一曲面积分方程和数据方程,重建曲面变化。在数值实现中,所谓的不适定逆问题在Tikhonov意义上被正则化。初步的数值结果表明,该方法是有效的,具有广阔的应用前景。

Electromagnetic Imaging of Random Rough Surface Profiles
In this work, an efficient algorithm for the reconstruction of a one dimensional dielectric random rough surface profile is presented. First the synthetic scattering field data is obtained by the solution of the direct problem through the conventional surface integral equations. Then the same surface integral equations together with the data equation are solved in an iterative fashion to reconstruct the surface variation. In the numerical implementation, the so called ill-posed inverse problem is regularized in the sense of Tikhonov. Preliminary numerical results show that the method is effective and promising.
