The “cumulant” method for solution of problems of wave propagation in random media


The “cumulant” method for solving problems of radiation propagation in randomly inhomogeneous media is described. Integral expressions for statistical moments of the wave complex amplitude in general form with the Feynman representation of Green’s function of the quasioptics parabolic equation have been obtained in the framework of the “cumulant” method. It was shown that taking into account some approximation of the processes of radiation multiple scattering in the “cumulant” method allows us to obtain expressions for statistical moments of intensity to an accuracy sufficient to restore the lognormal distribution function.
