摘　　要：电磁环境计算是战场电磁环境预测仿真系统的核心,为了准确预测不同环境下的电波传播特性,从复杂地形条件展开研究,给出一种基于PE模型的电场强度计算方法,仿真比较了辐射源在不同地表类型下的传播损耗,仿真预测了复杂地形条件下电波传播特性,仿真结果表明地表电磁特性对传播损耗的影响较小,相比于地表电磁特性,不规则地形对电波传播影响更为明显。The core of battlefield electromagnetic environment is electromagnetic environment calculation. In order to predict radio propagation characteristics in different environment, the calculation method of electric field intensity based on PE model are given on complex terrain. The propagation loss of radiation source is compared through simulation in different surface of the earth on complex terrain. The influence o f electromagnetic properties is analyzed for radio propagation. The radio propagation properties are predicted through simulation under complex terrain. The simulation results show that the surface electromagnetic properties is less influence on propagation loss and irregular terrain is more influence on radio propagation.
