Abstract

Cylindrical Wave Approach is applied to the scattering by a cylinder placed below a rough surface, and combined to Small Perturbation Method in the first-order approximation. In the theoretical approach, a surface with arbitrary profile is dealt with. As to the numerical solution, two alternative implementations of the surface are proposed: a sinusoidal profile and a periodic surface with samples from a Gaussian roughness spectrum. The developed method can be applied to the simulation of scattering by buried objects in a realistic environment with natural unevenesses.
