ABSTRAKT

Expressions for the second and fourth field moments which account for the solar wind flow structure are obtained with the Feynman path-integrals method. The expressions for scintillations of power spectra for the radiation received by a single antenna and by two spatially separated antennas are obtained and analyzed. For different solar wind models it was shown that the method of the dispersion analysis of phase speed, along with the scintillation method, allows to most fully investigate the solar wind flow structure at distances from the Sun exceeding 1 AU. This method enables to define not only the presence of solar wind flows of various speeds but also their extent and parameters.

SCHLÜSSELWÖRTER: interplanetary medium, scintillation spectrum, scintillation cross-spectrum, spectrum of interferometer response power fluctuations
