The intensity fluctuations of light scattered from a simple particle aggregate system consisting of two dipole-like particles separated by a fixed distance and floating freely in space are calculated numerically and analyzed statistically. The behavior of two statistical parameters, the second-order factorial moment of the intensity fluctuations and the probability of obtaining zero cross-polarized intensity, are studied as a function of both the particle polarizability and the interparticle distance. Effects of multiple-scattering processes on these statistical parameters are accounted for in particular.
