简要分析了战场电磁环境,针对科学构建战场电磁环境系统这一难题,提出了适合战场大区域、多种辐射源,并考虑地形、气象等影响因素的战场电磁环境数字仿真构建方法。该方法借助抛物方程、地理信息系统、神经网络等理论、方法构建战场电磁环境。最后应用该方法基于福建沿海某地真实地理环境与气象条件进行了仿真实验,实验结果与电波传播理论吻合。实验结果表明,该方法切实可行,具有实际应用价值。
War field electromagnetic environment has been briefly analyzed here. Aiming at the difficulty in construction of war field electromagnetic environment system, a method of quantitative constructing war field electromagnetic environment, involving the elements like broad war field, mutli-radiation source, the effect of terrain and meteorology, has been put forward here. By means of parabolic equation, geographic information systems, neural network and other theories or methods, war field electromagnetic environment is established. Finally a simulation in some area of Fujian province with true geographical and meteorological circumstance has been done with this method. The simulation results are consistent with radio wave propagation＇ s theory, which proves the feasibility and practical application value of this method.
