Abstract: In this paper, we propose a method and present the results of modeling fluctuations of transionospheric signals during propagation under conditions of intermittent ionospheric turbulence. The effects of intermittent fluctuations of the medium are studied using a non-Gaussian multifractal phase-screen model. A significant effect of non-Gaussian phase fluctuations on the statistical characteristics of the field on the Earth is demonstrated. In particular, an increase in the field coherence radius and a decrease in the scintillation index with an increase in the intermittency degree of phase fluctuations on the screen are revealed while the spatial spectrum of phase on the screen is kept the same. The possibility of solving the inverse problem of estimating the parameters of a multifractal model of stochastic phase perturbations on the screen by measuring the characteristics of the signal behind the screen is discussed.
