面向区域目标的多星协同对地观测任务规划问题

我国在轨对地观测卫星数目的不断增多和卫星对地观测需求的日益复杂化,要求利用多星协同完成对大面积区域目标的快速观测和观测数据的及时更新。针对这一新问题,提出了问题的求解框架,并在分析国外目前采用的区域分割方法的基础上,设计了一种改进的基于卫星、星载遥感器参数和区域目标形状特征的观测活动构造和处理方法,对多星协同观测区域目标具有一定作用。

Cooperative mission planning problem for area targets observation by multi satellites

With the increasing number of our on-orbit earth observing satellites and the complication of satellite observing re- quests,cooperation of multiple satellites is required to rapidly complete the coverage of big area targets and duly update the observation data.For such a new problem,a resolving framework was proposed,and an improved generation method of observing activity which considered the parameters of each satellite and its on-board sensor and the character of the area shape was designed based on analysis of the current area segmentation methods.The improved method lays a good foundation for cooperative observation of target area by multi- ple satellites.
