[文摘]:Consideration is given to wave scattering by artificial small-scale irregularities formed by the heating of the F-layer by high-power short-wave radio waves vertically incident on the ionosphere. Numerical results are presented on the depolarization of the scattered field in the case when the incident beam goes beyond the ionosphere and a backscattered signal is observed on the ground. The results obtained illustrate the effect of the anisotropy of the correlation function of small-scale ionospheric irregularities on the depolarization of backscattered signals. (B.J.)
