Physical optics polarization scattering matrix for a top hat reflector

The polarization scattering matrix for a cylinder on a circular disk is derived subject to the physical optics (PO) approximation. The multiple scattering between the cylinder and the circular disk ground plane is obtained by invoking image theory, and is expressed as a bistatic return from the cylinder and its image, due to the image field. Results for a particular case are evaluated and compared with measurements. >
