DETECTION OF SCHUMANN RESONANCE IN THE IONOSPHERE F REGION
-
摘要: 利用Aureol-3卫星在电离层F层高度上(650km左右)对电离层电场扰动与电子密度扰动的观测数据进行分析处理,在高纬电离层F层高度上可以检测到舒曼共振现象.根据等离子体参数,可以认为,发生在这个高度上的舒曼共振现象与L模式的波传播有关,舒曼共振的基频是与电子密度的大尺度不规则性有关,谐波分量与正向密度梯度相关.Abstract: In this paper, simultaneous measurements of electron density and ELF elec-tric field by Aureol-3 satellite have been analyzed using high frequency resolutionspectral and cross-bispectral techniques. The detailed analyses of the data shows: first, the peaks in the power spectra of the electric field components are seen at theSchumann resonance frequencies in the high latitude ionospheric topside F regionand second, the harmonics are associated with positive density gradients.
