Abstract-Electromagnetic waves scattering in turbulent anisotropic collision magnetized ionospheric plasma is investigated using complex geometrical optics approximation.Correlation function of the phase fluctuations of scattered radiation is obtained taking into account both electron density and magnetic fields fluctuations. The features of the angular power spectrum of scattered radiation are investigated analytically and numerically. The expressions of broadening of the spatial spectrum have been obtained for both powerlaw and anisotropic Gaussian correlation functions of electron density fluctuations. Gaussian spectral function takes into account the axial ratio of the field-aligned irregularities and the angle of inclination of prolate irregularities with respect to the external magnetic field. The variance of the phase and scintillation level of scattered radiation are calculated numerically for F -region irregularities of the ionosphere. The conditions of non-fully and fully developed diffraction patterns have been determined.

“…Investigation of statistical characteristics of scattered radiation in randomly inhomogeneous magnetized plasma is of a great practical importance. Statistical characteristics of the angular power spectrum (broadening and displacement of its maximum), scintillation effects and the angle-of-arrival of scattered electromagnetic waves by turbulent anisotropic collision magnetized ionospheric plasma layer for both power-law and anisotropic Gaussian correlation functions of electron density fluctuations were investigated analytically in the complex geometrical optics approximation on the basis of stochastic eikonal equation and numerically by statistical simulation using the Monte Carlo method [8][9][10]. The geomagnetic field plays a key role in the dynamics of the plasma in the ionosphere.…”

Abstract-Statistical characteristics of scattered electromagnetic waves by turbulent magnetized plasma slab with electron density and magnetic field fluctuations are considered via the perturbation method and boundary conditions. Magnetic field fluctuates both in magnitude and direction. Analytical expressions for the component of scattered electric field, correlation functions of the amplitude and phase fluctuations, and also the phase structure function for arbitrary correlation functions of fluctuating plasma parameters are derived. The obtained results are valid for near and far zones. Under equal conditions, at strong magnetic fields, electron density fluctuations play the important role and in this case the imposed magnetic field decreases fluctuation intensity of the ordinary and extraordinary waves. Numerical calculations of statistical characteristics of scattered radiation were carried out for anisotropic Gaussian correlation function
