Paper Abstract

In the paper the focused Gaussian beams diffraction from random surfaces which obey first- order Gaussian statistics is considered. The analytical expressions describing the probability density function and the correlation function of dynamic speckles intensity fluctuations and phase for different relations between the surface and the coherent beam parameters have been derived. The results of numerical simulation of focused coherent beam scattering for a small number of scatterers are discussed. The range of parameters, when the scattered field complex statistics are close to Gaussian ones, has been determined. Dependence of statistical characteristics of diffracted radiation on the correlation length and the standard deviation of random screen phase fluctuations has been studied.
