摘　　要：针对BVR防空作战的特点,提出基于Marichal熵和Choquet模糊积分的BVR防空作战威胁评估方法。首先,建立威胁评估优势函数模型,优化了方位角、进入角、距离、能量、效能优势函数,并增加了目标战役价值为威胁评估的因素;然后,针对各威胁因素之间的相关性,依据Shapley值,利用Marichal熵算法求解gλ模糊测度,确定各优势函数的重要程度,并通过Choquet模糊积分对各优势函数进行综合,实现威胁评估。经仿真计算验证,该方法合理、有效。Aiming at characteristics of Beyond Visual Range air defense combat,a new threat assessment method is proposed based on Marichal entropy and Choquet fuzzy integral.Firstly,superiority functions of threat assessment are constructed.Superiority functions such as azimuth,enter angle,distance,energy,efficiency are optimized,and,goal campaign values are added.Secondly,aiming at interdependence among threat factors,Marichal entropy calculates gλ fuzzy measures with Shapley values and weight of each superiority function are achieved.Then,Choquet fuzzy integral synthesizes each superiority function,sequentially,threat assessment is achieved.Finally,simulation results have verified the rationality and effectiveness.
