基于信息熵和TOPSIS法的目标威胁评估及排序

摘要

A method for threat assessment of aerial targets was proposed based on information entropy and TOPSIS to overcome the shortcomings of the existing assessment methods. A criterion system for threat assessment of aerial targets was founded at first. The threat factors, including angular velocity and stealthy degree, were determined. In order to consider both the subjective factors and objective factors, the combinatorial factor was used for determining the weight of the index. Finally, the TOPSIS was used to calculate the threat assessment. The experiment results demonstrated that this method is feasible and rational.%针对现有空战目标威胁评估方法中存在的不足,提出了一种基于信息熵和TOPSIS法的空战目标威胁评估方法.首先建立了空战目标威胁评估指标,确定了角度、速度、隐身等威胁因子；为综合考虑评估中的主客观因素,采用了组合权衡因子确定最终权重；最后采用TOPSIS法作为威胁评估的解算方法,进行仿真验证,结果证明了该方法的有效性及合理性.
