Evalution Bandwidth of Optical Signal via Statistical Moments of Random Phase Screen

Abstract

The majority of the works are dedicated to the specific problem, for instance, scattering from the rough surface although, the general theoretical bases of the statistical and spectral characteristics of the scattered light for the light of non-Gaussian statistics have not been studied so far. The signals with such statistics are produced when the characteristic scales of the refraction factor is in comparison with the size of illuminated region. In the present paper, we discuss the method of signal processing for analyzing first and second order statistical moments of electromagnetic radiation.
