Date of Defense 1993-05-15 Availability restricted AbstractShadowing of random surfaces is accounted for by multiplying the Kirchhoff
electric current density by a shadowing function. The shadow-corrected
incoherent intensity is computed in the backscatter direction and is found to be
proportional to the probability of a specular point being illuminated from the
source. This probability is computed numerically using an infinite series of
integrals, developed by Ricciardi and Sato, and by Monte Carlo computer
simulations. The results obtained are compared to the analytic approximations of
Wagner and Smith, which neglect correlation between the shadowing points and
the shadowed point. Assumptions made by Wagner are explained using the
infinite series of integrals. Furthermore, comparison is made to Wagner's results
which include correlation between the shadowed point and the shadowing point.
