摘要

According to the large and complex computation of electromagnetic environment,a parallel computing method based on irregular terrain model (ITM) is proposed.This method captains the 3D scalar field to describe the electromagnetic environment and adopts a static task distribution algorithm based on row to avoid the redundancy of DEM computing,it can assure the load balance between computing nodes.The experiments show that this parallel method has high parallel efficiency and can suffice the need of electromagnetic environment computation effectively.%针对复杂电磁环境仿真中算法复杂、计算量大的特点,构建了一种基于不规则地形模型(irregular terrain model,ITM)电波传播模型的复杂电磁环境并行计算方法.该方法采用三维标量场的数据组织方式描述复杂电磁环境.在并行计算关键的任务分配阶段依据ITM模型的计算特点和三维标量场的数据组织方式,采用了以标量场列为基本单位的静态任务分配方法,有效地避免了地形提取的冗余计算,保证了节点间的负载平衡.经实验验证,该算法并行效率较高,能够有效地满足不规则地形条件下的复杂电磁环境快速计算的需要.
