Modeling of EM Wave Coherent Scattering From a Rough Multilayered Medium With the Scalar Kirchhoff Approximation for GPR Applications

This article presents a new asymptotic modeling of electromagnetic (EM) wave coherent scattering from a rough multilayered medium, based on the scalar Kirchhoff-tangent plane approximation. The proposed EM model is developed to simulate a realistic ground-penetrating radar (GPR) signal that considers the interface roughness of the multilayer. It allows us to investigate the influence of the interf...
