摘要
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 satel-lite 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 segmen-ted into different strips. Simulation results show that the method proposed can improve the ob-serving efficiency of polygon target compared with the traditional method, and can be used as a reference for remote sensing satellite autonomous mission planning.
