考虑遥感卫星成像任务规划时对多边形区域目标的分解问题,提出了一种基于卫星视场角的区域目标动态分解方法.首先根据卫星的轨道特性,计算卫星对区域目标的可见时间窗口;在可见时间窗口内,计算卫星对区域目标的最大、最小有效观测角度;再以卫星的视场角为角度偏移量,同时考虑幅宽的动态变化,将区域目标分解成相互平行且幅宽不等的条带.仿真结果表明:文章提出的区域目标动态分解方法,能够将区域目标有效分解,与传统的区域目标分解方法相比,可明显提高遥感卫星对区域目标的观测效率.研究结果可为遥感卫星自主任务规划技术研究提供参考.%Considering the segmenting problem for remote sensing satellite imaging of polygon target,a dynamic segmenting method of polygon target based on satellite FOV is proposed.Firstly,the time windows of polygon target are calculated according to the characteristic of satellite orbit,and then the maximum and minimum effective observing angles of polygon target are confirmed by the time windows.Lastly,considering the dynamic swath,polygon target is segmented into different strips.Simulation results show that the method proposed can improve the observing efficiency of polygon target compared with the traditional method,and can be used as a reference for remote sensing satellite autonomous mission planning.
