Abstract
We derived analytical expressions for the correlation of intensity fluctuations of a partially coherent Gaussian Schell-model plane-wave pulse scattered by deterministic and random media. Our results extend the study of correlation of intensity fluctuations at two space points for scattered stationary fields to that at two time points for scattered non-stationary fields.

Summary
Scattering is of great importance in physics, astronomy, chemistry, meteorology, biology, and in other fields. Scattering of electromagnetic fields from a medium which fluctuates both in space and in time has been studied extensively in recent years [1–9]. The study of partially coherent pulses has been developed from conventional Gaussian correlation function to nonconventional correlation functions. There have been several attempts to study the correlation of intensity fluctuations at two space points of the scattered field, and it was found that information about the scattering potentials of deterministic and random media may be obtained from the measurement of the correlation of intensity fluctuations [20–22]. We considered correlation of intensity fluctuations at two time points of the scattered field for a partially coherent Gaussian Schell-model plane-wave pulse. We derive analytical expressions for the correlation of intensity fluctuations of a partially coherent Gaussian Schell-model plane-wave pulse scattered by deterministic and quasi-homogeneous random media
