针对传统空战威胁评估方法难以直观地给出目标威胁状况及发展趋势的缺陷与不足，提出基于区间数雷达图的可视化空战威胁评估方法。该方法首先通过区间数与反三角函数确定并归一化目标属性决策矩阵；然后运用区间交叉熵法和群组层次分析法确定目标属性权重，并对威胁进行分级；最后在改进雷达图方法基础上，建立可视化空战威胁评估数学模型。仿真分析表明，该方法能够使决策者在正确的评估结果前提下直观地分析出各目标威胁状况与趋势。%Considering that the traditional air combat threat evaluating methods are difficult to intuitively reflect the situation and development trend of the target threat,a method of visualization threat assessment for air combat based on interval-radar chart is proposed.Firstly,the normalized decision matrix of target attribute is determined by the interval number and anti-trigonometric function.Then,the weight of target attribute is calculated by the methods of interval cross entropy and the group decision analytic hierarchy process,and the target threat is graded.Finally,the mathematical model of the visualization threat assessment for air combat is established with the improved radar chart method.The simulation results show that the method intuitively ana-lyzes the situation and development trend of each target threat under the premise of the correct assessment re-sults.
