摘要
本文以电离层等离子体参量的平均背景模式计算为基础,给出一种电离层短波射线轨迹计算方法。供短波通信系统、工作于短波段的其它系统(如HF雷达的目标定位系统)及有关研究工作使用参考。
In accordance with the requirement of ground communication system of remote distance for short wave band, on the basis of the model calculation of the mean background of ionospheric parameters, a method is presented for calculating the trace of short wave ray in ionosphere. The work is mainly concentrated on two aspects. First of all, bacause the frequency of short wave is relatively higher, the magnetic and collision effects in refractive index are neglected, so that general ray equations are simplified. In the second place, a method of calculatitng he first-order partial derivative of ionospheric plasma parameter is presented. The calculation of the partial derivative is on the basis of model result of parameters of each ionospheric layer, that is, on the basis of mean background of ionospheric parameters.It can be used in HF communication system, and other short wave system such as target position system of HF radar, etc.
