电离层等折射指数面速度剖面的无线电反演研究

本文对三种反演等值面运动速度的方法:(1)等效镜反射面的方法;(2)Bertel等提出的积分反演方法;(3)同时利用寻常波和非常波多普勒频移的反演方法进行了讨论。对给定的电子密度分布模型(卡普曼层)和等折射指数面扰动速度剖面进行了上述三种反演方法的自我检验。结果表明同时使用寻常波和非常波的多普勒数据的反演方法的结果的最好。 

A Study of Radio Inversive Method of Ionospheric Isorefractive Index Surface Motion Velocity Profile

In the first part of this paper,three inversive methods for the ionospheric isorefactive index surface motion velocity profile are discussed summarily.In the second part of this paper,the theoretical value of Dopple shift of echoes for a given electron density distribution profile model (Chapman Model) and a given velocity profile of isorefractive index surface are calculated.Then,the velocity profiles are calculated with three inversive methods to examine the method itself respectively.The results show the method using O-wave and X-wave's Doppler shift data simultanosuly is the best moreover the responsibility of the disturbance in the space where there is no trace in the dopplerionogram (below h_min) for the Doppler shift of echoes can be calculated with this method.
