我们开发了一种测量极光吸收的新方法，只使用一个被动的HF接收器检测大量现有的HF传输。虽然这些来源的位置、强度和时间表尚不清楚，但它们的数量之多使它们能够进行统计处理。对源的分布进行建模，并使用Foppiano和布拉德利[1983]的波传播模型，得到了接收器处接收信号的模拟模式，该模式是一天中时间的函数，与观察到的模式吻合得很好。
We develop a new method of measuring auroral absorption using only a single passive HF receiver detecting a large number of existing HF transmissions. Although the locations, strengths, and timetables of these sources are not known, their large number allows them to be treated statistically. Modeling the distribution of the sources and using the Foppiano and Bradley [1983] model for the propagation of the waves leads to a simulated pattern of received signals at the receiver as a function of time of day which agrees well with the observed pattern.
