基于改进空战威胁评估模型的权重计算方法比较

Comparision on Weights Calculation Methods Based on Improved Air Combat Threat Assessment Model

针对多无人机(UAV)任务网协同空战态势威胁评估问题,在现有基本模型基础上增加考虑气象环境对威胁评估要素的影响和无人机的自主可靠性系数两个实际因素,提出一种改进的超视距空战威胁评估模型;同时,应用串联电阻分压法、改进AHP法和熵权法分别计算融合模型中各威胁指标的权重系数;进而,在考虑己方战机对敌方战机综合威胁与优势的基础上,介绍了战机协同空战目标分配的基本方案。最后,应用上述3种权重计算方法进行空战威胁仿真计算,计算结果表明改进空战威胁评估模型可有效改善空战决策性能。

The aim of this research is to solve the issue of situation threat assessment for muhi- uavs cooperative air combat, a improved threat assessment model of BVR air combat is proposed with considering the influence of environment factors to the related assess elements and the independent reliability coefficient of the drones. The weight factors determined individually by using series resistor voltage,improved AHP and entropy weight method. Based on the consideration of both threat and dominance, a target assignment of muhi-uavs cooperative air combat is introduced. Compared the threat simulation calculation based on the above three kinds of weight methods ,the results showed that the improved method of threat assessment model improved the credibility of the model.
