ABSTRACT

The statistical quantities of interplanetary scintillations at decameter wavelengths (scintillation index, power spectrum, cross-correlation function, probability density function) for the strong and weak scattering cases are estimated by analyzing the observations of 4C21.53 radio source scintillations. The obtained results can be used to test the models applied for analyzing interplanetary scintillations data at decameter wavelengths. The high efficiency of the DSP-z wide-band digital spectrum analyzer for interplanetary scintillations observations at decameter wavelengths is shown.
