Abstract:

The Physical Optics approximation is employed in the derivation of a closed form expression for the Radar Cross Section RCS of a flat, polygonal, perfectly conducting PEC plate, located over a dielectric, possibly lossy half space. The well-known four-path model is invoked in a first order approximation of the half space contribution to the scattering mechanisms. Numerical results are successfully compared to a reference, Moment Method solution. The analytical expressions derived can facilitate very fast RCS calculations for realistic scatterers, such as ships in a sea environment, or aircraft flying low over the ground.
