[1] Radiotomographic imaging of the artificially disturbed midlatitude ionosphere with cassiope and parus satellites / V. E. Kunitsyn, E. S. Andreeva, A. M. Padokhin et al. // 14th International Ionospheric Effects Symposium IES2015, Alexandria, VA, USA. — United States: United States, 2015. We present the results of the radiotomographic imaging of the artificial ionospheric disturbances obtained in the recent experiments on the modification of the midlatitude ionosphere by powerful HF radiowaves carried out at the SURA heating facility. Radio transmissions from PARUS and CASSIOPE recorded at the specially installed network of three receiving sites were used for the remote sensing of the heated ionosphere. We discuss the possibility to generate AGWs with special regimes of ionospheric heating (with the square wave modulation of the effective radiated power at the frequency lower than or of the order of the Brunt-Vaisala frequency of the neutral atmosphere at ionospheric heights during several hours) and present radoitomographic images of the spatial structure of the disturbed area of the ionosphere corresponding to the directivity pattern of the heater, as well as the spatial structure of the wave-like disturbances, which are possibly heating-induced AGWs, diverging from the heated area of the ionosphere. The spatial period of observed disturbances is 200–250 km and they are easily traced up to a distance of 700–800 km from the heated region. [ DOI ]
