Abstract
One of the approaches to solving the inverse problem of determining the parameters of ionospheric disturbances is the multiple solution of the two-point problem with the subsequent comparison of the simulation results with experimental data (ionograms). However, this approach is usually associated with significant calculation time costs, which makes it impossible to process large arrays of sounding data. The method described in this article makes it possible to quickly determine the horizontal velocity of the ionospheric disturbance by descent rate of an additional U-shaped trace moving to lower virtual heights on the vertical sounding ionograms: in order to calculate the velocity, it is proposed to use the results of the ray tracing obtained for the reference background profiles with disturbances superimposed on them.
摘要--解决确定电离层扰动参数的逆问题的方法之一是多解两点问题,然后将模拟结果与实验数据(电离图)进行比较。然而,这种方法通常需要花费大量计算时间,因此无法处理大量探测数据。本文介绍的方法可以通过在垂直探测电离图上向较低虚拟高度移动的附加 U 形轨迹的下降率,快速确定电离层扰动的水平速度:为了计算速度,建议使用在参考背景剖面上叠加扰动后获得的射线追踪结果。
