摘　　要：推扫式成像卫星短时采集数据量大.针对用户时效性要求高且星上处理资源有限的情况,星上处理算法难以灵活平衡精度与效率,设计并研制了一种面向推扫式成像卫星的智能处理软件系统.构建星上处理配置库,柔性组装各处理算法模块,最大限度优化卫星资源、完成用户定制化任务,并针对缓存空间不足问题,提出了虚拟栅格融合技术.基于“北京三号”C卫星星座开展了智能处理软件系统的在轨验证.结果表明:系统在满足用户需求、处理资源约束的同时,提升了处理精度和速度,并探索了以任务为核心的随动生成处理流程的在轨数据处理和信息提取新模式,提高了卫星对地观测能力和服务能力.Push-broom imaging satellites collect large amounts of data in a short time,and the on-board processing algorithm is difficult to flexibly balance accuracy and efficiency due to high user time efficiency requirements and limited on-board processing resources.A push-broom imaging satellite oriented intelligent processing software system was designed and developed.It constructed the on-board processing configuration library,flexibly assembled each processing algorithm module,fully optimized the satellite resources,completed user customized tasks,and proposed virtual grid fusion technology for insufficient buffer space.The in-orbit verification result based on the BJ-3C Satellite constellation shows that the intelligent processing software system meets the user requirements and processes resource constraints,while improving the processing accuracy and speed.It also explores a new mode of in-orbit data processing and information extraction with task-centric follow-up generation processing flow,which improves the satellite′s Earth observation and service capabilities.
