论文摘要
已经提出了一种简单的方法来确定来自VLF无线电信号的测量值的Mesosphere Heights的声学波浪（AGW）。对于相对较短的路径（小于$ \ sim $ 2000 km），可以从无线电信号振幅的测量值中获得简单的关系，以估算AGW中性密度波动。在波浪跳跃近似中，我们将无线电信号反射高度的波动与AGW诱导的大气气体的垂直位移相关联。使用这些关系，我们可以在Mesophere Heights上恢复AGW的一些特性。
A simple method has been proposed to determine acoustic-gravity wave (AGW) properties at mesosphere heights from measurements of VLF radio signals. For relatively short paths (less than $\sim$ 2000 km long), simple relations are obtained for estimation of AGW neutral density fluctuation from measurements of amplitudes of radio signals. In the wave-hop approximation, we relate the fluctuations in radio signal reflection height with AGW-induced vertical displacement of an elementary volume of atmospheric gas. Using these relations, we can recover some properties of AGWs at mesosphere heights.
