摘要
针对多星协同观测条件下的区域目标划分问题,提出了基于成像卫星在不同观测角度下对区域目标不同覆盖范围的动态划分方法。依据卫星每次经过区域目标时对区域的可观测范围,按照星载遥感器的不同观测角度对区域目标进行分解。采用立体几何计算卫星在某侧视角度下对区域目标的覆盖范围。采用MapInfo软件计算多个条带对区域目标的综合覆盖率。仿真试验表明,在采用相同调度算法的情况下,基于本文提出的区域划分方法,能够明显提高多星对区域目标协同观测的效率。
The coordinating multi-satellites observing of polygon targets was studied in the paper.An ameliorative method of segmenting polygon target was proposed based on the range of satellites＇observation on targets by different angles.During the segmenting,the solid geometry was used to count the range,and the factors such as sensor geometry and path of aviation were considered in the method.MapInfo was used to count the rate of the range of satellites＇observation on targets.Experiments showed that this approach could improve the efficiency of the polygon target observing.
