摘要
任务规划是敏捷卫星执行对地观测任务的有效支撑和重要保证,为深刻理解和准确把握敏捷卫星任务规划研究中的关键问题,对国内外相关研究进行了总结分析,并对下一步研究进行展望。首先阐述了敏捷卫星任务规划问题的描述要素、分类方法和求解难点,然后从点目标、区域目标、立体成像、长条带目标4个方面梳理了敏捷卫星任务规划的研究进展;最后分析了目前研究中存在的成像模式研究较少、规划模型不完善、评价方法单一等问题,并结合发展需求,提出需要从多种成像模式下的任务规划、敏捷卫星组网协同和自主任务规划、高效的求解算法等方面展开进一步研究。
Mission planning is an essential support and important guarantee for an agile satellite to implement earth observation missions.To deeply understand and accurately grasp key issues of agile satellite mission planning,the paper makes conclusive analysis on the relevant researches home and abroad and brings out prospects for further research.First of all,the paper illustrates the description elements,classification method and difficulty in solving process of agile satellite mission planning,and then concludes the research progress of agile satellite mission planning in four respects including point target,regional target,three-dimensional imaging and strip target.In the end,the paper analyzes the issues existing in current research like less imaging mode research projects,incomplete planning model and a single assessment method.Combining with the development needs,the paper proposes that the further research should be conducted in respects like mission planning under multimode imaging,agile satellite networking and collaboration and independent mission planning and efficient solving algorithm.
