Scintillation spectra of multiple scattered radio waves in the ionospheric plasma

Abstract

Statistical characteristics of radio waves scattered in the turbulent ionospheric plasma are investigated analytically by modify perturbation method taking into account both polarization coefficients and diffraction effects of both ordinary and extraordinary waves. Numerical investigations are carried out for anisotropic Gaussian correlation function containing anisotropy coefficient and the angle of inclination of elongated plasma irregularities with respect to the geomagnetic lines of forces. Scintillation level is analyzed for different parameters characterizing anisotropic irregularities using experimental data.
