Abstract: Apparatus of numerical-analytical modeling of refraction cosmic radiation in gravitational field of mass objects in presence random plasma inhomogeneities and gravitational noise is developed on based beam approximation and theory of perturbations. The propagation of radiation in the stochastic gravitational field was considered as process in Euclid’s space with the effective refraction index of vacuum expressed by gravitational potential. The results of calculating of stochastic blurring of gravitational lensing effects are presented at depending on the position of radiation source and receiver for various types of inhomogeneities of cosmic space.

Keywords: electromagnetic radiation, geometrical optics, gravitational field, gravitational and plasma inhomogeneities.
