Аннотация

The usage of spaced antennas suggests a more or less quantitative approach to the estimation of the speed of solar wind medium. However in the past, the group delay time (GDT) and the known distance between the beams were mainly used to determine the speed [1]. Fluctuations of the flow velocity in time domain, determined within such an approach, allow a qualitative assessment of the turbulent flow regime [1,2]. The extensive experimental material processed with techniques based on the measurement of GDT indicates that a uniform and isotropic regime of solar wind turbulence is confirmed at distances of more than 15–20 solar radii [3] only. However, the capabilities of data processing and interpretation techniques developed based on the GDT are not enough to study of the reasons for deviations of the turbulent regime (from Kolmogorov’s regime expected) at a close distance to the Sun, as they take the flow as a whole averaging all estimates over it. Therefore improvement of the technique itself is crucially required in order to make a finer analysis of the solar wind flows within the region in question.
