Radar cross section of a complex-shaped cavity with a loaded metal diaphragm

Abstract

We propose a method for calculating the monostatic radar cross section of a two-dimensional complex-shaped cavity, which contains a plane-layered medium in the form of a loaded metal diaphragm placed on a dielectric layer. The method is based on the combined boundary-integral/modal method and the variational Galerkin method with the use of dyadic Green's functions. The results of calculating the angular dependences of the radar cross section for various parameters of the plane-layered medium are presented. Restrictions of the applicability and potential for further development of the method are indicated.
