摘　　要：针对传统的空战多目标威胁评估不适于第四代战斗机超视距多目标空战威胁评估的问题,提出了一种新的适合第四代战斗机超视距多目标空战的威胁评估方法。该方法在传统多目标威胁评估的基础上,考虑空战高度和第四代战斗机隐身性能,分别运用模糊优选法和区间层次分析(IAHP)法解算主客观权重,进而得到综合权重区间,并运用改进的TOPSIS法进行多目标威胁评估研究。仿真结果表明该算法的有效性和合理性,适合于第四代战斗机超视距多目标空战的威胁评估。The traditional method is not adaptable for threat assessment of beyond-visual-range multi-targetcombat of the fourth generation fighter,thus we proposed a new threat assessment method.Based on the traditionalmulti-target threat assessment method,the new method took combat height and stealth performance of the fourthgeneration fighter into account,calculated out the objective weight and subjective weight of threat assessmentindex respectively by fuzzy optimal method and IAHP,and finally gained the comprehensive weight.The improvedTOPSIS was used for the multi-target threat assessment.An application example is given and the results show thatthe method is reasonable,effective,and suitable for the threat assessment of beyond-visual-range multi-targetcombat of the fourth generation fighter.
