Scattering by cylindrical targets buried in a ground with rough interface

The scattering problem of a plane-wave by a set of cylinders buried under a rough surface is considered. As solving technique, an analytical solution based on Cylindrical Wave Approach is proposed, in the cases of perfectly-conducting or dielectric objects. Small Perturbation Method is employed to deal with the rough surface profile. The presence of multiple cylinders is useful both to study the case of interacting scatterers and to simulate objects with arbitrary cross-section. Numerical results relevant to a surface with sinusoidal profile are presented. © 2011 IEEE
