SCINTILLATION CHARACTERISTICS OF SPORADIC IRREGULARITIES OVER XINXIANG
-
摘要: 本文介绍新乡1989和1990年夏季ES层不均匀体引起的ETS-II卫星136MHz信号幅度闪烁的观测结果。揭示了闪烁出现与f0Es的关系、闪烁强度和持续时间的概率分布、准周期性闪烁特点以及闪烁谱特征。导出了ES层不均匀体的尺度和漂移速度等物理特性。Abstract: According to the results of the 136MHz signal amplitude scintillation from ETS-IIsatellite observed at Xinxiang in the summers during 1989-1990,a statistical relation between scintillation occurrence and f0Es is given with the help of digital ionosond observations. The quasi-periodic scintillation properties are shown.The probabilities of scintillation intensity and of the duration, as well as the features of scintillation spectrum are obtained from the statistical study.Physical characteristics of irregularities, such as the size and the drift speed are deduced from the observations.
