Radar cross section of simple objects in the presence of an infinite conducting plane

This paper analyzes the radar cross section (RCS) of two simple geometric shape objects - a sphere and a flat plate - in the presence of an infinite perfect conducting plane. Simulations are carried out using the software CST Microwave Studio^®, and it´s shown how the presence of a conducting plane changes the original RCS of the individual objects at free space as they penetrate the conducting plane. The normalized RCS has a typical behavior and can be modeled by simple equations for each object as a function of its relative height to the conductive ground plane.
