The invention provides a regional scanning coverage task planning method and system for a two-dimensional scanning satellite constellation, and the method comprises the steps: S1, collecting the data of a target region, and discretizing the target region into a point set; s2, calculating and processing related parameters; the parameters comprise discrete region benefits, satellite transit time sequences and single-satellite detectable time; s3, if all the preset satellites are planned, outputting a planning result; otherwise, repeating the step S2. According to the method, the satellite can preferentially scan the undetected part in the regional target, so that more regional areas can be scanned in limited time, and full-coverage scanning of the regional target can be quickly and effectively realized; the task planning method for area scanning is simple and clear in process, can be implemented only through numerical calculation, does not need a complex simulation tool, and has high practicability.
本发明提供了一种二维扫描卫星星座的区域扫描覆盖任务规划方法及系统,包括步骤S1:采集目标区域的数据,将目标区域离散为点集;步骤S2:计算并处理相关参数;所述参数包括离散区域效益、卫星过境时序和单星可探测时间;步骤S3:若所有预设卫星都已规划完毕,则输出规划结果;否则,重复步骤S2。本发明能够让卫星优先扫描区域目标中未被探测的部分,实现在有限时间内扫描更多区域面积,快速有效地实现区域目标全覆盖扫描;本发明涉及区域扫描的任务规划方法过程简单明确,仅通过数值计算即可实施,无需借助复杂的仿真工具,具有较强的实用性。
