摘　　要：针对地球同步轨道带的目标高重访探测需求及目标形状和姿态对探测效果影响的问题,文章结合天体视星等计算公式,给出了球体和方体两类典型空间目标视星等分析计算方法,归纳出视星等随光照角和目标姿态的变化规律,提出了方体目标最低星等的隐蔽姿态及其光学隐身策略,并针对隐蔽姿态和隐身场景的探测需求,提出基于超同步轨道的GEO目标天基近实时探测方法,且完成了仿真分析验证,结果表明:双星可实现我国国土上空地球同步轨道带目标的近实时探测,可为我国未来GEO目标天基探测发展提供参考。There is a high revisit demand for the detection of geosynchronous targets,which is further influenced by the shape and attitude of the targets.In this paper,based on the calculation formula of the photometric magnitude of celestial bodies,the analysis and calculation methods of the photometric magnitude of two typical space objects,sphere and cube,are given.The variation of the photometric magnitude by illumination angle and target attitude is summarized.The concealment attitude of the lowest photometric magnitude of cube and its optical stealth scene are proposed.Finally,a space-based and near real-time detection method of geosynchronous objects based on super-synchronous orbit is proposed to meet the detection requirements of the concealment attitude and stealth scene.Results show that two satellites can realize a near real-time monitoring of geosynchronous orbit over China,and it can provide a reference for the future development of GEO objects space-based detection over China.
