Abstract:
In the work, it is shown, that the time dependence of the amplitude-frequency characteristic of reflected signal has been named «amplitude map» (A-map). Alternate vertical stripes typical for A-map are likely to be associated with focusing properties of traveling ionospheric disturbances. Based on the analysis of experimental data the loops with focusings, loops without focusings and focusings without loops are revealed. For research of space-time structures, moving ionospheric disturbances, capable to result in focusings, the numerical synthesis of A-maps and ionograms have executed. It is shown, that the occurrence of sickle-type structures is determined by parameter describing «intensity» of heterogeneity. At construction of ray trajectories the method bi-characteristic method and its generalization is used: Lukin-s method of extended bi-characteristic systems.
