Abstract
Scattering from correlated points of a randomly rough surface is studied. The variables of the roughness: heights and slopes of neighboring points on a randomly rough surface are correlated. The contribution from this correlation is appreciable, and should be taken into account for computation of the scattered intensity from a rough surface. A general approach and analytic formula are provided.
