Abstract:

This paper examines the regions of validity that apply to the use of various models for describing rough surface scattering. The first area to be examined is how a small slope condition allows an integral representation of the physical optics PO cross section to be formed that does not require the high frequency geometric optics GO restriction. Next, for forward scattering, consider the extension of the roughness dependence of the PO scattering cross section from the case of Gaussian surface and correlation to a range of surface with different height statistics and correlation functions. This dependence is then examined for the small perturbation method SPM regime as well. Finally, the forward scattering PO results are extended to the case where the azimuthal angle does not equal 0 deg.
