摘　　要：战情模拟仿真与多维态势效果展示技术研究是开发现代化军事作战训练系统的必要条件之一。提出了一种基于金字塔模型的电磁态势仿真方法,通过由上到下分层对仿真区域地形进行四叉树剖分,建立改进的金字塔模型并将其纵向分层、横向分块,实现各层模型间的密切联系和连续平滑过渡,达到将仿真区域地形进行精细化三维建模的效果。对于上下相邻两层模型中的结点来说,父级结点之间地形格网间距大于子结点、采样点少于子结点,因此在绘制仿真场景地形时效率更高,具有较高的工程应用价值。The research of war situation simulation and situation display system is the necessary condition for designing intelligent military training system.An electromagnetic situation simulation method is presented based on pyramid model,by dividing the terrain layer by layer into quadtree,the pyramid model is divided into vertical layers and horizontal blocks to achieve the close contact and continuous smooth transition between layers,so as to achieve the effect of fine simulation of 3D terrain scene.For the nodes in the adjacent two layers,the terrain grid distance between the parent nodes is larger than that between the child nodes,and the number of sample points involved is less than that of the child nodes,so the rendering efficiency is higher,and has higher application value.
