The invention discloses a spacecraft orbit threat avoidance decision-making method based on FGCM, belongs to the technical field of aerospace science, and solves the problem that autonomous decision-making is difficult for spacecraft orbit threat scenes such as non-cooperative targets when a spacecraft operates in orbit. The spacecraft avoidance behavior strategy model based on the FGCM is established by defining the input and output nodes and the state value rule of the model, the task scene where the spacecraft is located is predicted based on the FGCM, the influence of the uncertainty of the autonomous decision making process is reduced, the gray causal association weight of the model is optimized by using the genetic algorithm, and the decision making efficiency is improved. The reliable threatening behavior avoidance strategy of the spacecraft is obtained, and the spacecraft can autonomously generate the corresponding behavior strategy for avoidance when facing non-cooperative target threatening.

    一种基于FGCM的航天器轨道威胁规避决策方法,属于航天科学技术领域,解决航天器在轨运行面对非合作目标等轨道威胁场景难以自主决策的问题;本发明通过定义模型的输入和输出节点及其状态取值规则,建立了基于FGCM的航天器规避行为策略模型,基于FGCM对航天器所处的任务场景进行预测,降低了自主决策过程不确定性的影响,利用遗传算法优化模型的灰色因果关联权值,获取可靠的航天器规避威胁行为策略,实现了航天器在面对非合作目标威胁时能够自主产生相应的行为策略进行规避。
