RESONANCE GENERATION OP LOW-FREQUENCY DISTURBANCES IN POLAR IONOSPHERE. Molchanov 0.A., Shvartaburg A.B. The effects of inhomogeneous heating of polar electrojet in the field of powerful radiowave are discussed in this paper. The important role of eddy currents and chargee separation exiting low-frequency oscillations is illustrated here. Eigenmodes of these oscillations are obtained from geometric dimensions of heating zone and is in the range of 0,05-2,0 kHz. Possibility of electric field and ionoaphere parameters estimation on low- frequency signals characteristics is demonstrated here. EXPERIMENTAL INVESTIGATION OP RADIO WAVES SCATTERING IN IONOSPHERE AFFECTED BY POWERFUL RADIOEMISSION. Pex'tsovakij R.A., Tkachenko B.V. The experiment run on radioline Zapolyarnny-Umba with the middle point in the region of ionosphere disturbed by powerful radioemission showed that at some conditions the "forward" scat tering of radio waves on the non-homogenetiea of ionosphere stimulated by powerful radioemiasion ін observed. ANISOTROPIC SCATTERING FROM AN ARTIFICIALLY MODIFIED F-REGIQN OF IONOSPHERE AT Iff AND TOP BANDS. Kalitenkov N.V., Lukosyas ¥u„P„, Miroshnicov Yu.G.s Pertsovakij R.A.* Siekkinen K„H., Timopheev E.E., Uryadov V.P., Uspanskij M.V. Anisotropic VHP scattering measurements of an artificially modified F-region of ionosphere are described in the paper. The measured effective scattering cross-sections in the frequency of two values for impulse equipment and for the equipment of conti- nious emission either are given in the work. The results are dis cussed and compared with the earlier foreign works on ionosphere heating. EFFECTS OBSERVED DUE TO VERTICAL SOUNDING OF AURORAL IONOSPHERE DISTURBED BY POWERFUL HP RAttlOEMISSION. Royzen A.M. The analysis of Loparakaja observations at vertical Bounding of auroral ionosphere region disturbed, by powerful HP emLssion ia given in this paper. The effectи are mostly similar with those obtained for middle-latitude ionosphere. However, ЕВрГѲѲд die- 89
