释放诱饵是典型弹道导弹中段突防措施之一,对诱饵与真弹头的威胁度进行评估也因此成为导弹防御系统实施拦截的首要前提.考虑弹头与诱饵的位置、速度、RCS及红外辐射强度等目标特性不同,采用模糊隶属函数和G.A.Miller 9级量化理论对弹头与诱饵的威胁属性进行量化,建立了基于离差最大化的导弹中段目标威胁度多属性评估模型,给出了计算实例.计算结果表明,采用此方法能够有效确认威胁度最大的目标,满足弹道中段目标的威胁度评估需要.
The release of bait is one of the typical methods of preventing the mid-section of a typical ballistic missile, and the evaluation of the threat of bait and bullet becomes the first precondition for the implementation of the missile defense system. Consider the position, velocity, RCS and intensity of infrared radiation The target characteristics are different, the threat attributes of warheads and decoys are quantified using the fuzzy membership function and the GAMiller 9-level quantitative theory, and a multi-attribute assessment model of the mid-range target threat degree based on the maximization of dispersion is established, and a calculation example is given. The results show that this method can effectively identify the most threatened targets and meet the needs of the mid-ballistic target threat assessment.
