Abstract

The results of signal shape study for backscatter ionosphere sounding (BS) depending on conditions of radio waves propagation and electric properties of earth surface are given. The experimental BS data obtained in different seasons of the year on the basis of multifunctional chirp ionosonde developed in ISTP SB RAS were analyzed. For analysis and interpretation of BS signals on ionograms the modeling results of chirp signal characteristics under backscatter ionosphere sounding in the framework of waveguide approach were used. The most characteristic types of ionograms were identified and conditions for the appearance of one or another type were established depending on the time of day, the season, the direction of sounding and the medium state.
