针对空战态势评估中, 常权求和带来的信息动态性不够灵活的问题, 提出了动态变权重的近距空战态势评估方法。该方法在优势函数的基础上, 加入空战能力指标, 改进了评估指标体系; 并且依据贝叶斯理论实时确定态势类型, 综合空战态势变化特点, 根据变权理论, 动态调整评估指标权重。通过真实的空战数据仿真实验, 验证了该方法在空战态势评估中的可行性和有效性。仿真结果表明, 动态变权重的评估方法能够有效改善常权求和引起的信息动态性差的问题。

To solve the problem that the information dynamics in constant weight summing is not flexible enough in air-combat situation assessment,a dynamic variable weight method is proposed for the situation assessment in close-range air combat.Based on the advantage function,the evaluation index system is improved by adding the air-combat capability index.Moreover,according to the Bayesian theory,the situation type is determined in real time,the characteristics of air-combat situation changes are integrated,and the weight of the evaluation index is dynamically adjusted according to the variable weight theory.The feasibility and effectiveness of this method in air-combat situation assessment are verified by the simulation experiments with real air combat data.Simulation results show that the dynamic variable weight evaluation method can effectively prevent the problem of poor information dynamics caused by constant weight summing.
