Abstract :
The statistical properties of random rough surfaces are related to the basic radius-of-curvature condition for applying a physical optics scattering model. The relation between different surface slope regimes and the use of approximate physical-optics models are discussed. Included is how scattering from surfaces with other than small slope conditions restricts the use of such approximations
