A Compact Strong-scatter Scintillation Model

This document describes numerical solutions to the 4-order moment equation for scintillation under strong scatter conditions. It is well known that scintillation depends on the parameters that describe the structure size distribution, and the Fresnel radius. However, in an unconstrained fixed power-law environment, the theory can be formulated in terms of a single parameter. In effect, different combinations of perturbation strength, propagation distance, and frequency produce exactly the same results. This paper exploits this relation and extends it to two-component power-law spectra.
