Grazing angle scattering of electromagnetic waves based on an improved two-scale model

Abstract: WOSInternational audienceRemote sensing applications require developing accurate models to predict radar bistatic scattering from random rough surfaces. In this context, an improved two-scale model (TSM) is developed. The simplest TSM (TSM1) combines the first order small perturbation method (SPM1) with geometrical optics (GO) to be able to cope with both the small- and large-scale components of the surface. To get improved results at grazing angles and better depolarization estimation, we include the effects … Show more

“…These methods are TSM and SSA. The TSM [18]- [20] handles the large and small roughness by using two kinds of coordinate bases: several local bases for the small roughness and a global basis for the large roughness. The global basis is independent of the surface, while the local bases are dependent on it, since the z-direction of these bases coincides with the normal to the surface.…”
