A study on the electromagnetic backscattering from wind-roughened water surfaces

In this paper we report the results of a study regarding the backscattering from wind-roughened water surfaces. The reference profile data has been de ducted bg an experiment held at the University of Heidelberg: circular wave tank facility. The scattering theory is based on a fractal description of the surface and a combined use of the Kirchhoff approximation and the small perturbation method (SPM). Thf scattering results are tested versus the on es obtained via the periodic-surface moment method. The study shows the rel iability of the novel approach.
