The bistatic scattering from the natural rough surfaces in X and Ku bands

The scattering of waves by random rough surfaces has important applications in remote sensing of oceans and land. At low grazing angles and ranges involved, the existing data base is quite limited. The problem of developing a model for rough surfaces is a very difficult one, since, at best, the scattering coefficient σ⁰ is dependent upon (at least) radar frequency, geometrical and physical parameters, incident and observation angles, as well as polarization. In this paper, the development of a theoretical two-scale model describing bistatic reflectivity is presented. The author also gives the numerical results computed for the bistatic radar cross-section from random rough surfaces, especially from the sea surface
