Statistical properties of a stochastic electromagnetic pulse scattering by a quasi-homogeneous random medium

The scattering of a stochastic electromagnetic plane-wave pulse on a Gaussian-correlated, quasi-homogeneous random medium within the accuracy of the first-order Born approximation is investigated. Based on the mutual coherence matrix, the analytical formula for the average intensity, degree of temporal coherence and degree of polarization of the scattered field in the far zone is derived. The numerical calculations are performed in order to show the influence of the pulse duration, temporal coherence length, degree of polarization of the incident pulse and the properties of scatterer on the average intensity, degree of temporal coherence and degree of polarization of the scattered field. The validity of the results is also interpreted physically.
