基于区间交叉熵的时序动态空战威胁评估

Time Series Dynamic Air Combat Threat Evaluation based on Interval Cross-entropy

针对传统空战威胁评估方法难以结合整个空战态势变化趋势的问题,提出基于区间交叉熵的时序动态空战威胁评估方法.首先,建立动态空战威胁评估体系;然后,采用指数分布法确定时间序列权重;采用区间交叉熵法确定目标属性权重;最后,建立基于区间交叉熵的时序动态空战威胁评估数学模型.通过仿真分析表明,该方法是科学、合理的,而且相比于传统方法所得评估结果更加具有说服力.

As the traditional methods of the air combat threat evaluation are difficult to be combined with the develop trend of the total air combat situation, a method of time series dynamic air combat threat evaluation based on interval cross-entropy is presented. Firstly, the index system of the dynamic air combat threat evaluation is established. Then, the time series weights are gained by the method of exponential distribution, and the target attribute weights are calculated by the method of interval cross-entropy. Finally, a mathematical model of the time series dynamic air combat threat evaluation based on interval cross-entropy is established. And the simulation indicates that the method is scientific and reasonable, but also the evaluation results are more persuasive compared with the traditional methods.
