摘要
针对自然灾害监测、海洋目标监视等多星协同探测应用场合,首先分析了多源卫星信息在轨融合处理的必要性,其次总结了国内外卫星数据在轨处理的研究现状和存在的问题,然后在此基础上从星上探测、通信和计算资源出发,分析了适应在轨处理的在轨自主任务规划、目标信息表征、多源卫星信息目标在轨关联、多源卫星信息在轨特征融合、星地协同数据处理与动态交互等多源卫星信息在轨融合处理的相关问题和关键技术,最后,给出未来发展趋势展望。
On-board information fusion for multi-satellite which is based on spatial computing mode can improve the satellites’capability such as the accuracy of detection,the confidence of recognition,the precision of position and the coverage of spatial-temporal for disaster monitoring,maritime surveillance and other emergent or continuous persistent observing situations.Firstly,the necessity of on-board information fusion is analyzed.Secondly,the on-board processing developments are summarized and the existing problems are discussed.And thirdly,the key technology and concepts of on-board information fusion are studied in the fields of target feature representation,target association,feature-level fusion,autonomous mission planning and other issues.Finally the future developments of on-board information fusion are studied and discussed.
