针对地空导弹系统的威胁自动判断问题，基于对目标指示雷达保障距离以及三种拦截区间中系统作战效能的分析，提出了目标距离威胁指数和目标类型威胁指数的概念，进而建立了一种连续型的威胁判断决策模型，并给出了每个区间火力打击的排序标准。该模型可用于目标指示雷达威胁自动判断、系统作战预案自动选择决策和作战方案自动优化决策。

Aiming at the self-estimation of threat to the SAM system, and basing on the analysis of support distance of the target acquisition radar and operation efficiency of the system in three intercept sections, a distance-threat index and a type-threat index of the target are proposed, and a threat-estimation decision-making model is established, and a standard of fire-striking order in each section is put forward. This model can be used in self-estimation of threat of the target acquisition radar, self-selection of decision-making of the system operation plan and self-optimization of decision-making of the operation plan.
