Popis:	Three-moded random ionospheric HF channel of propagation has been investigated. The description of the channel has been given in terms of the scattering function and the appropriate codes for numerical calculations allowed assessment of the relative contributions of different modes in the scattering of the full field have been developed. In particular, the effect of overlapping of these contributions in the scattering function has been studied in the domain of Doppler spread -- group delay time. The dependence of this effect on the bandwidth of the signal and the geometry of propagation was investigated.
