ABSTRACT

The potential of the dispersion analysis technique is discussed in application to interplanetary scintillations observed from two sites (UTR-2 and URAN-2 radio telescopes). By combining analyses of the frequency dependences shown by velocities of cross-spectral harmonics of the scintillations and of their power spectra, it proves possible to recover the basic parameters of the interplanetary plasma along the line of sight. In the framework of a layered model of the medium, layer thicknesses, densities and velocities can be estimated, as well as the power index of the spatial spectrum and inner scale of the turbulence.
