Abstract
In the review, the results of experimental studies of spatial structure of small-, middle-, and large-scale plasma density perturbations induced in the ionosphere by its pumping by powerful HF O-mode (ordinary) radio waves, are analyzed. It is shown that the region with induced plasma density perturbations occupied all ionosphere body from its E-region up to the topside ionosphere in the height and it has the horizontal length of about of 300–500 km. Peculiarities of generation of artificial ionosphere irregularities of different scale-lengths in the magnetic zenith region are stated. Experimental results obtained under conditions of iono-sphere periodical pumping when the generation of travel ionosphere disturbances is revealed are also discussed.
