SCATTERING FROM A CONDUCTING CYLINDER ABOVE A LOSSY MEDIUM

Scattering from conducting objects above a lossy medium is a problem of current interest concerning the radar detection and identification of targets near the ground. Using a Green's function approach, in a way similar to that used to treat scattering from underground objects, the problem of electromagnetic scattering from conducting cylinders located above the ground is considered. The unknown surface current J(r) of the conducting cylinder is determined through the resulting integral equation and the far-field in the air is evaluated employing the steepest descent method of integration. Numerical results for the far-field region of the overground scatterer are plotted and conclusions concerning the influence of the various parameters of the problem are disucssed.
