oai:ri.kharkov.ua:article-7292013-02-16T19:54:34Z Spectral Features of HF Signals from the EISCAT Heating Facility in Europe and in Antarctica Спектральные особенности КВ сигнала нагревного стенда EISCAT в Европе и Антарктике Zalizovski, A. V. Kascheev, S. B. Yampolski, Yu. M. Galushko, V. G. Beley, V. S. Isham, B. Rietveld, M. T. Brekke, A. Blagoveshenskaya, N. F. Kornienko, V. A. Analysis is presented of the propagation of signals from the Tromsø heating facility that have been received during the international measuring campaign of 26-30 October, 2002 at three sites in Europe and in Antarctica. Two components with different characteristics (“mirror reflected” and “scattered”) were observed in the signal spectra. Their nature is explained. The variations in the signal intensity as well as in the Doppler frequency shift recorded at the widely separated sites show a high level of correlation. It is shown that the Doppler frequency variations can be associated with physical velocities of motion inside the scattering volume and/or with variations of plasma density in the underlying region. The spatial structure of drifts of the plasma irregularities is reсonstructed. Рассмотрены особенности распространения сигналов нагревного стенда EISCAT (г. Тромсё), принятых в трех пунктах в Европе и Антарктике во время международной измерительной кампании 26-30 октября 2002 года. В спектрах сигналов выделены две компоненты с различными характеристиками – “зеркальная” и “рассеянная”. Объяснена природа их появления. Отмечена высокая корреляция вариаций интенсивности и доплеровского смещения частоты рассеянной компоненты в приемных пунктах, разнесенных на большие расстояния. Показано, что вариации частоты могут быть связаны как с физическими скоростями движения внутри рассеивающей области, так и с вариациями плотности плазмы под ней. Восстановлена пространственная структура дрейфа плазменных неоднородностей.
