地磁场条件下短波三维射线追踪仿真研究
|
摘要
为了分析电离层不均匀特性和地磁场对电波传播路径的影响,从Haselgrove射线方程出发,采用国际参考电离层和国际地磁参考场模型计算等离子体参数和磁参数,运用龙格库塔法求解射线方程,实现了短波三维射线追踪。通过采用三维射线追踪对均匀和不均匀电离层模型下射线路径计算并描迹,对比分析得出:不考虑电离层不均匀性将对射线路径造成较大地面距离误差。采用三维射线追踪对有无地磁场影响下的射线路径进行计算,仿真结果表明,地磁场存在时射线路径发生偏离且偏离方向及大小均不同。
To analyze the effect to wave propagation path by the inhomogeneity of the ionosphere and the geomagnetic field,in accordance with the Haselgrove ray equation,the international reference ionosphere model and the international geomagnetic reference field model is established,the plasma parameters and the geomagnetic parameters are computed,the Runge-Kutta method is used to solve the ray equation,then the shortwave 3D ray tracing is carried out.The ray paths in the homogenous and inhomogeneous ionosphere are obtained and traced by the 3D ray tracing,the comparative analysis results show that more ground range error is brought out without regard to the inhomogeneity of the ionosphere.With and without the geomagnetic field is existed,the ray paths are obtained by the 3D ray tracing,when the effect the geomagnetic field is considered,the simulation results show that the ray paths are not in the same plane,the azimuth of the ray paths is shifted and the shifting direction and scale is different.
