本文应用射电星和卫星闪烁的弱散射薄屏理论，以严格的数学方法，对赤道扩展F条件下由火箭和雷达测量导出的等离子体密度结构进行了观测。结果表明，底侧扩展F是能够产生中等闪烁在VHF，但不是在千兆赫频率。然而，耗尽等离子体密度的上升区域，例如最近几篇出版物中描述的区域，被证明具有可能导致强烈的甚高频闪烁以及千兆赫范围内闪烁的特性。
The weak scattering, thin screen theory of scintillation of radio stars and satellites has been applied, in a mathematically rigorous way, to the observations of the plasma density structure deduced from rocket and radar measurements during equatorial spread F conditions. It is shown that bottomside spread F is capable of producing moderate scintillation at VHF, but not at gigahertz frequencies. Upwelling regions of depleted plasma density however, such as those described in several recent publications, are shown to have properties that could cause intense VHF scintillations as well as scintillations in the gigahertz range.
