摘　　要：战场电磁环境分布状态预测是有针对性地构建电子对抗训练复杂电磁环境的前提。目前的战场电磁环境分析方法不能对电磁环境分布状态进行解析预测,使得电磁环境的构建、控制和评估缺少理论依据和具体指标,针对这一问题,将熵的概念应用于战场电磁环境频谱分布预测。介绍了基于熵的战场电磁环境复杂度研究现状,组成论对战场电磁信号环境的组成、复杂性进行了分析,给出了战场电磁信号环境时间、空间、频谱占有差异的复杂程度计算公式,以战场电磁兼容为约束条件,使用最复杂原理,预测了战场电磁信号环境的频谱宽度的分布函数,最后,进行了仿真计算,仿真结果与理论预测吻合。Distribution status prediction of battlefield electromagnetic environment is necessary precondition when we construct complex electromagnetic environment for electronic countermeasure training,.However,the present analytical method can not be used to predicate electromagnetic environment distribution status,which is lack of theoretic basis and operational standard of constructing,controlling and e-valuating electromagnetic environment.In order to overcome this,the conception of entropy is used to predicate spectrum distribution in battlefield electromagnetic environment.Firstly,present research status is reviewed on complexity of battle-field electromagnetic environment based on entropy.With the constitution theory,the constitution and complexity of battlefield electromagnetic signal environment are investigated.The complexity computation formulas are proposed for represen-ting time,frequency and space occupation difference.Then,with maximum com-plexity Principle,frequency occupation distribution function of battlefield electro-magnetic signal environment is predicated under the condition of battlefield electro-magnetic compatibility.Lastly,simulation results are given,which match the theo-retical computation well.
