| 摘 要： | 信息对抗是卫星信息系统面临的严重威胁,在对抗条件下其工作效能必然会有一定程度的下降.以卫星侦察系统为例研究了卫星系统效能损伤评估方法.在对卫星侦察过程进行分析的基础上建立了卫星侦察系统效能故障树,并引入故障等级和逻辑算子的概念,提出了一种基于多态故障树分析的评估方法,采用仿真方法进行顶事件概率计算.最后将其应用于某卫星侦察系统在信息对抗条件下的效能损伤评估,并给出了结论.

| Abstract: | Information countermeasures severely decrease the working effectiveness of satellite systems.The approach to evaluate the damage of satellite system effectiveness is developed,which is instanced by a satellite reconnaissance system.The damage tree of satellite reconnaissance system effectiveness is established based on the analysis of satellite reconnaissance process.The damage classes and logical operators are introduced.Because the damage states are divided into three classes,the multistate system theory ... |
