Some Peculiarities of the Angular Spectrum of Radio Waves Scattered in the Polar Ionospheric Plasma

This paper investigates propagation and multiple scattering of small amplitude radio waves propagating in the polar terrestrial ionosphere. Double-peaked shape of the spatial power spectrum is described by second order statistical moments containing complex refractive index, polarization coefficients, orientation of homogeneous external magnetic field, ionospheric conductivities, anisotropic parameters of electron density inhomogeneities, and the distances between observation points. Features of the “Double-Humped Effect” are considered analytically in absorptive statistically anisotropic magnetoactive plasma. Numerical analyses are carried out for anisotropic Gaussian correlation function applying experimental data for polar ionospheric F-layer. The results have been obtained analytically for the first time and could find practical Application in remote sensing of the terrestrial ionosphere and in communication.
