Paper considers some aspects of the relationship between scintillation level of scattered radiation
and anisotropic plasma irregularities in the collision turbulent magnetized plasma. Analytical
calculations are carried out using modify smooth perturbation method taking into account both
diffraction effects and polarization coefficients of both ordinary and extraordinary waves.
Correlation function and the wave structure function of the phase fluctuations are obtained for
arbitrary correlation function of electron density fluctuations. Analytical and numerical
calculations of the second order statistical moments are carried out for the anisotropic Gaussian
correlation function taking into account both anisotropy factor and the inclination angle of the
elongated plasma irregularities with respect to the external magnetic field. Scintillation level and
the power spectrum of the intensity fluctuations are analyzed for different parameters
characterizing anisotropic irregularities.
