摘要

Second order statistical moments of scattered ordinary and extraordinary waves in magnetized turbulent plasma are investigated analytically and numerically using the smooth perturbation method. Correlation functions of the phase fluctuations are obtained in the principle and perpendicular planes for arbitrary correlation functions of electron density fluctuations. New features of both the Double-humped effect and scintillation spectra are analysed for anisotropic Gaussian and power-law wavenumber spectra taking into account diffraction effects. The scintillation level is estimated for different anisotropy factors and the angle of inclination of prolate irregularities with respect to the external magnetic field. Scintillation minimums of a temporal spectrum are calculated for different thicknesses of a plasma slab taking into account the movement of rigid irregularities and diffraction effects for scattered ordinary and extraordinary waves in turbulent magnetized plasma.
