Scattering from rough plates

Abstract

The radar cross section (RCS) of rough rectangular plates was studied using Monte Carlo simulations with the method of moments (MM) and physical optics (PO), and by computing the mean power pattern. For both the MM and PO based simulations a plate in the xy plane is represented by a collection of small triangles. The roughness of the surface is obtained by randomly displacing the z coordinates of the triangle nodes. The main focus of the study was to look at the effects rough surfaces have on the off principal plane regions.
