电离层短波三维射线追踪及其应用研究
|
摘要
从三维射线追踪的Haselgrove方程出发,采用龙格-库塔法求解沿射线路径的电波传播参数,实现了电离层短波数字三维射线追踪,重点对数字三维射线追踪具体实现的一些关键问题处理进行了深入分析研究。本研究工作是结合传播工程技术问题开展的,以一类具体的电离层模型,给出了三维射线追踪在一些传播工程中的具体应用。
In accordance with the 3-D Haselgrove ray equation,the propagation parameters along the ray path are resolved by the Runge-Kutta method,and the 3-D Ray Tracing of the short wave in the ionosphere is realized.In particular,the emphasis is put on the specific application of the 3-D Ray Tracing in ionospheric propagation,and several problems of importance to the method are discussed in detail.At last,Based on a type of model ionosphere,the application of the 3-D Ray Tracing in some propagation project is described.
