Magnetically oriented irregularities of the ionosphere and super dual auroral radar network (SuperDARN)

摘要

The paper considers a possibility of investigation of magnetically oriented irregularities in the ionosphere using a SuperDARN system. To determine the parameters of such irregularities, the authors suggest applying backscattering of decameter waves. As a rule, scattering on magnetically oriented irregularities of the ionosphere is considered to be an aspect one directed along the Earth magnetic field lines. It is shown that under certain conditions, such as propagation path orientation along the Earth magnetic field lines, polarization and frequency of the emitted wave, not only aspect but also resonance backscattering of decameter waves is possible. Results of experimental observations of such scattering on magnetically oriented irregularities of the ionosphere in Kamchatka are presented.
