内容記述 | The magnetic field strength at the fundamental frequencies 50Hz and 60Hz, of power line radiation in the topside ionospheric region has been observed by the instrument aboard the satellite “OHZORA” in the global area. The observation has started on June 1, 1984, in order to measure the magnetic field strength of the power line radiation in the topside ionospheric region over the eastern Asia. The observation instrument consists of a loop antenna and a receiving unit, which can receive the fundamental frequencies (50 and 60Hz) of power line radiation by means of three narrow-bandwidth filters. It is identified that the origin of the background noises of magnetic fields observed at these frequencies is due to the ELF hisses propagating from the outer plasmasphere. By means of the statistical procedure, the background noise field strength at 50 or 60Hz can be determined in comparison with the strength at 55Hz. If the magnetic field strength is higher than the level of ambiguity, the corresponding position can be specified as the reasonable position of power line radiation. According to the result of observation, the power line radiation at 60Hz radiated from the Japan Islands seems to spread over the wide area. The observation results also show that the power line radiation over the eastern China reveals a correlation between the statistically reasonable positions of magnetic field strength at 50Hz and the possible distribution of power lines on the ground. | |||||
