Generalization of ionospheric tomography on diverse data sources: Reconstruction of the three-dimensional ionosphere from simultaneous vertical ionograms, backscatter ionograms, and total electron content data

Autor: S. V. Fridman, L. J. Nickisch

Publikováno v: Radio Science. 36:1129-1139

An ionospheric reconstruction method is developed that is capable of simultaneously utilizing information from all possible sources of ionospheric measurement. We describe the method and demonstrate its performance on ionospheric data collected by an

Linear and nonlinear prediction techniques for short-term forecasting of HF fading signals

Autor: O. V. Fridman, K. C. Yeh, Steven J. Franke, S. V. Fridman

Publikováno v: Radio Science. 32:989-998

There exist two major mechanisms which are responsible for the fading phenomenon at HF frequencies. They are the multiple-mode interference and distortions due to the ionospheric irregularities. Fading time series produced by the first of these mecha

Two-frequency correlation function of the single-path HF channel: Theory and comparison with the experiment

Autor: O. V. Fridman, Steven J. Franke, K. C. Yeh, K. H. Lin, S. V. Fridman

Publikováno v: Radio Science. 30:135-147

The two-frequency mutual coherence of HF electromagnetic field fluctuations caused by ionospheric irregularities in an oblique radio path is studied. The single scattering approximation is first developed and then extended to stronger field fluctuati

Plasma sheet as a shock wave: Dynamic predictions of the model

Autor: S. V. Fridman, E. V. Voronov

Publikováno v: Journal of Geophysical Research. 99:11243

A study is made of some dynamic implications of our earlier model of large-scale magnetospheric structure, in which the plasma sheet is a collisionless shock wave (Fridman and Voronov, 1993). According to our calculations, the polar boundary of the a
