Full textAbstract
Abstract : A new solution is developed for the problem of scattering from a randomly rough, perfectly conducting, interface having many scales of roughness. A review of the capabilities and limitations of first order smoothing (FOS) and normalized first order smoothing (NFOS) approximations are first carried out. By combining the concepts contained in NFOS approximation with those of the conventional composite surface scattering model, it is possible to develop a new method that is mor robust than its components. The key step is to split the regions of current interaction on the rough surface into near and far zones; the effect of the latter is mainly one of large scale surface shadowing while the former accounts for small scale diffraction. Comparisons with the conventional composite surface scattering model are carried out and a number of improvements are noted. Further improvements in the model, if needed, appear to be tractable. ...
