摘　　要：针对航空集群在突防场景下的射频(radio frequency,RF)隐身性能评估问题,提出基于正态波动犹豫模糊集(normal wiggly hesitant fuzzy set,NWHFS)相关系数的评估方法。首先,推导出NWHFS相关系数表达式;然后,通过分析航空集群与单个载机平台RF隐身评估的不同,提取出集群RF隐身性能评价参数,并得到隶属度参考点公式;组织决策者根据隶属度参考点给出NWHFS决策矩阵;最终,通过计算待评估场景与参考点集之间的相关系数,定量地评价不同场景下航空集群的RF隐身性能,并由此确定RF隐身性能排序。以四机集群为研究对象,对突防场景下的3种情景进行了仿真验证,证实该评估方法的有效性。Aiming at solving the problem of the swarm radio frequency(RF)stealth performance evaluation of aircraft swarm under penetration scene,an evaluation method based on the correlation coefficient of the normal wiggly hesitant fuzzy set(NWHFS)is proposed.Firstly,the NWHFS correlation coefficients expression is derived.By analyzing the differences between the RF stealth evaluation problems of aircraft swarm and single carrier platform,the parameters of the swarm RF stealth performance evaluation are extracted,and the formulas of the membership degree reference point are obtained.Decision-makers give the NWHFS decision matrix according to the membership degree reference points.Finally,the correlation coefficient between the scenes to be evaluated and the reference point set is calculated to quantitatively evaluate the RF stealth performance of the aircraft swarm under different scenes,and to determine the RF stealth performance ranking.Taking the four-aircraft swarm as the research object,the simulation of three scenes under the penetration scene is carried out,which proves the validity of the evaluation method.
