Abstract


The research-based stochastic medium theory of wave propagation around the ionospheric irregularities on radio wave propagation and ionospheric irregularities drift velocity inversion -related research . International ionization layer reference model in accordance with the IRI2001 Antarctic Zhongshan Station over the ionospheric plasma data , and based on this data using the dual-band two-point mutual coherence function of the analytical solution , combined with numerical methods consider different power spectrum model the following is a more detailed study of the random medium spread through the ionosphere second-order statistical properties of the coherence length and coherence bandwidth with the changes in the characteristic parameters of the ionospheric irregularities . Rytov approximation and Markov process approximations for solving parabolic equations the scintillation index derived ionospheric radio wave propagation and numerical analysis , detailed discussion of the relevant parameters of the scintillation index , and were compared with the satellite observations . Finally, the intensity of the power spectrum analysis of the theoretical inversion of the drift velocity of the irregularities , and to verify the correctness of the results in accordance with the relevant literature .
