摘要
电磁环境计算是战场电磁环境预测仿真系统的核心,PE模型中只考虑了二维电波传播问题。基于GRID的二维地形剖面获取是PE模型三维电磁环境计算方法的基础,在此基础上文中研究了三维电磁环境计算方法的流程与步骤。采用ArcGIS软件中的ArcGlobe建立地理环境模型,给出了一种基于GRID型数字高程模型的三维电磁环境计算方法,分为地形剖面划分、剖面参数获取与计算、三维电磁场数据生成以及多辐射源电磁环境叠加4部分,有效地将二维PE扩展为三维情况,为仿真软件的设计实现奠定了基础。
The core of battlefield electromagnetic environment is electromagnetic environment calculation. Two-dimensional propagation is considered in PE model. Terrain profile acquisition on GRID is the basis for three-dimensional electromagnetic environment calculation on PE model. The three-dimensional electromagnetic environment calculation method based on GRID digital elevation model is given. The method is divided into terrain profile partition,profile parameters acquisition and calculation,three-dimensional electromagnetic data generation and multiple radiation source electromagnetic environment superposition. The two-dimensional PE model is extended to three-dimensional in laying the foundation for the simulation software design.
