摘　　要：人类持续的航天活动使得地球空间的人造航天器及非合作物体数量日益增加,太空安全保障与环境治理逐渐成为空间活动可持续发展的重要课题。空间目标的感知与测量是开展空间环境治理的前提条件。以航天器为平台进行全天目标远距离观测与编目、重点目标的抵近观测与成像是天基目标感知的重要方式。天基协同感知旨在通过多天基平台、多传感器联合感知的方式获取空间目标有价值的属性信息,在碎片和失效航天器预警、在轨卫星状态评估、在轨服务的测量与识别等方面发挥着重要作用。本文综述了近年来天基感知技术的发展情况,分析了空间目标天基协同感知中的关键技术,并对该技术未来发展方向进行展望。Continuing human space activities have led to increasing numbers of man-made spacecrafts and noncooperative objects in Earth’s space,which makes space security and environmental management gradually become important issues for the sustainable development of space activities.The perception and measurement of space targets are prerequisites for space environment management.It is an important means for space-based target perception to use spacecrafts as platforms for the long-range observation and cataloguing of targets throughout the day and for close-in observation and imaging of key targets.The space-based collaborative perception aims to obtain valuable attribute information of space targets by means of joint perception by multiple space-based platforms and sensors,and plays an important role in the early warning of debris and failed spacecrafts,the assessment of in-orbit satellite status,and the measurement and identification of in-orbit services.In this paper,the development of space-based perception technologies in recent years is reviewed,the key technologies in the space-based cooperative perception of space targets are analyzed,and the future development direction of these technologies is forecasted.
