防空作战电磁环境建模与仿真

Modeling and Simulation of Battlefield Electromagnetic Environment in Aerial Defence Warfare

以防空作战为背景,分析了战场电磁环境的构成要素,在建立各要素脉冲描述字模型的基础上,提出了基于脉冲流描述的电磁环境建模方法,构建了相应的仿真系统,完成了防空作战电磁环境的动态模拟。绘制出典型作战场景下电磁环境时域、频域、功率域的态势图,仿真结果表明电磁环境具有两个显著特点:动态性与相对性。建模仿真方法对战场电磁环境的仿真构建具有一定的借鉴意义。

The constituent elements of electromagnetic environment（EME） in aerial defence warfare were analyzed,and their pulse description word（PDW） models were established.Simulation system was then constructed according to the EME modeling method based on pulse flow description,which was applied in a specified aerial defence warfare scenario to obtain dynamic simulation of EME.The situation maps in time,frequency and power domain were provided to sufficiently reveal the variability and relativity of EME.The proposed modeling and simulation approach can use for references in constructing virtual battlefield EME for equipment efficacy evaluation application.
