Plane wave scattering on a reflector antenna located over an impedance plane

Abstract

The influence of an impedance plane on the efficient surface of diffusing (radar cross-section (RCS)) of a parabolic antenna is considered in this paper. The features of diffusing are analyzed on the basis of combination of the method of physical optometrists (of physical optics) and integral equations. It is shown that due to mutual reflections from the mirror antenna and the impedance plane, the RCS can double its angular sector. The results of numerical experiments are also presented.
