Mathematical modeling of effects of plasma and gravitational inhomogeneities in the structure of electromagnetic signals

The three-dimensional algorithm of calculation of the trajectory characteristics of electromagnetic signals in a random-inhomogeneous space plasma placed in the gravity field of difficult configuration has been suggested. The influence of the gravity on the signal propagation has been taken into account by the use of efficient index of refraction. The inhomogeneities of plasma have been defined by the model of spatial correlation function of fluctuations of index of refraction. Results of mathematical modeling of lensing of electromagnetic signals in the gravity field from several space objects have been provided. It is shown that, a significantly different spatial structure of ray field can occur in picture plane of the observer depending on the properties of the gravitational field and parameters of random plasma inhomogeneities.
