Abstract

A fast algorithm for reconstructing the profile of a random rough surface is presented. This algorithm uses the 3D electromagnetic waves scattered from rough ground surfaces to retrieve the unknown surface profiles. The proposed algorithm is based on merging a 3D fast forward solver and an efficient optimization technique. The preliminary results show the potential success of the inversion algorithm.
