摘　　要：针对高轨空间碎片的精准化跟踪及清除需求,文章提出一种基于星图背景的全自主捕获、观测及跟踪识别方法,依据恒星惯性空间位置不变性,通过连续帧图像数据比对实现恒星目标和非恒星目标分离,完成空间碎片目标识别。作为应用于高轨空间碎片捕获、观测的全自主双体制模式探测系统,在兼顾空间碎片捕获、观测的基础上,同时还具备恒星测姿功能,经过地面及在轨验证表明:在对高轨空间碎片跟踪过程中四元素结果稳定,恒星测姿结果稳定,可广泛应用于高轨空间碎片的跟踪与治理任务。In response to the requirements of accurate tracking and eliminating for high orbit debris,this paper proposes a fully autonomous method based on star image background from a new type of non-operative pose sensor(NOPS).This method is based on the invariance of star inertial space position,and achieves the separation of stellar and non-stellar targets through continuous frame image data comparison,supporting the completion of recognition task for high orbit space debris.As a fully autonomous dual body mode detection system applied to high orbit satellites for long distance debris target acquisition,it not only takes into account space debris discovery,but also has the function of star attitude measurement.after ground and in orbit verification,it has been shown that the four element results are stable in the tracking process of high orbit non-cooperative object.It can be widely applied to observe and govern high orbit space debris,especially space debris in synchronous orbits.
