Radar cross section of the cavity with a loaded metal diaphragm

We propose a method for calculating the monostatic radar cross section of a two-dimensional cavity containing a plane-layered medium in the form of a loaded metal diaphragm which is located between two dielectric layers. The method is based on the modal technique and dyadic Green’s functions. The numerical results for the angular dependences of the radar cross section are presented for various parameters of the plane-layered medium. Limitations of the method and the possibilities of its further development are pointed out. __________ Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Radiofizika, Vol. 51, No. 4, pp. 320–327, April 2008.
