Abstract:
The phenomena of ionospheric perturbations during the experiments between SURA and HAARP heating facilities with DEMETER satellite have been summarized, and the main disturbed electromagnetic signals have been found, including the radiated HF pump wave and sideband pump wave, enhanced VLF transmitter signals and extended frequency band, modulated ULF/ELF/VLF wave, ELF electromagnetic emissions, ULF resonant wave, perturbations in plasma parameters and precipitation of high energy particles. Then the occurrence frequency of each kind of phenomenon is studied, in which the radiated pump waves were with high occurrence probability of larger than 68%, while other disturbances detected by satellite were with low probability of smaller than 40%, and some even occurred occasionally under specific condition, owing to the effects of local ionosphere background and modulated mode, etc. Finally, combined with the orbit design and payload installation on China Seismo-Electromagnetic Satellite (CSES), some suggestions have been provided on future experiments between ionospheric heating facility with CSES on the basis of the statistical results, in order to avoid the problems and improve the successful experimental probability as much as possible.
