摘　　要：空间目标威胁评估是空间作战过程中的一个重要环节。结合空间武器对抗的特点,分析了影响空间目标威胁评估的主要因素,构建了空间目标威胁体系和威胁评估示意图,给出了空间目标威胁评估的指标。在威胁评估依据和原则的基础上,建立了基于指标隶属度与信息熵的威胁评估模型。通过实例应用表明,评估模型实现了空间目标威胁评估,为空间作战的指挥决策提供了依据。To assess the threat of space targets is an important part of space combat. Combined with the characteristics of space combat, the primary factors affecting the threat of space target are analyzed, the space targets system and threat assessment sketch map are built, and the space target threat assess- ment indexes are given. The threat assessment model is established on the basis of the basis and principle of threat assessment, which is based on the degree of membership and the information entropy. Finally, a numerical example is given to show that the model achieves the quantitative analysis of the space targets threat assessment and provides the foundation for making decision in space war.
