Abstract
The problem of diffusion of the two parallel rays within oblique propagation in a linear layer containing isotropic random inhomogeneities of the dielectric permittivity is considered. Based on the stochastic ray equations written in the coordinate system of the parabolic cylinder, the coefficients of the equation of Einstein-Fokker, describing the relative diffusion of the rays, are defined. The distribution law of the relative fluctuations of the directions of rays for the case when the initial distance between the rays is much greater than the radius of correlation of fluctuations of the dielectric permittivity, is obtained. It is shown that the distribution in the coordinate system used is valid in any point of the trajectory of the rays, which coordinates satisfy the conditions of the problem considered.
