Abstract

In this paper electromagnetic scattering from deterministic rough surfaces is described through analysis of radar images. Backscatter results are considered for 1-D random rough surfaces which satisfy an impedance boundary condition (IBC). Radar images of single realizations of random surfaces are formed through back-projection tomography. Detailed investigations of the images are also provided to clarify major and secondary scattering events, angular dependencies, and polarization effects, and a ray tracing analysis is performed to predict multiple scattering images. For an ocean-like surface, effects of surface length scale components are discussed
