为使指挥员准确认识战场电磁环境和进行正确的指挥决策，对战场电磁环境的复杂度评估问题进行了深入研究。总结了复杂度评估的基本方法，从作战使用的角度出发，提出了基于博弈值的评估方法，建立了评估模型，并给出了模型的最优混合策略解，分析了方法的可行性。通过对典型场景的评估计算证明，该方法适用于对抗双方有多种作战行动方式可供选择的情况下评估电磁环境的复杂程度，并可以得出最优作战行动概率，从而有效提高战场决策水平和作战训练水平。

To make the commander recognize the complicated electromagnetic environment and make correct decisionthe complexity evaluation of battlefield electromagnetic environment was studied.The common complexity evaluation methods was summarized at first.Thenan evaluation method based on value of a Game was proposed from the perspective of operational application.A model of evaluation was constructed and the solution under the optimal mixed strategy was given.The calculation of the scenario showed thatthis method can evaluate the degree of complexity while the both sides have multiple optional operation modes and make the optimized combat operation selectionthus can improve the decisionmaking and training effect.
