Exploring Interferences Arising in the Construction of GPR Responses from an Object Buried Between Two Rough Surfaces by GPILE Method.
Résumé
In this paper, we explore interferences arising in the electromagnetic scattering by an object buried inside a layer with two rough interfaces by using the GPILE method. We show that there are two categories of interferences in the echoes that make up GPILE: the interferences that are present whatever the chosen scenario and those that come from the geometry of the problem (distance between the three scatterers). In this last category, we can cite for example the interferences which come from the position of the object, more precisely from its depth, because an object closer to one of the surfaces would produce echoes which arrive almost at the same time as those of the nearby interface.
