The invention discloses a window minimum interval-based space target polling task autonomous planning method and system, and the method comprises the following steps: 1, carrying out the slicing of an obtained time window set, obtaining a time window slice set, and sorting the time window slice set according to the starting time; step 2, performing first round of solving: under the condition that constraint conditions are met, for each satellite, performing rapid solving by taking the minimum observation window interval as a task planning principle, and preferentially ensuring that each target is observed; and step 3, second-round solution: on the basis of the result of the step 2, repeated observation of a part of space targets can be realized by using the residual observation resources through the second-round solution. According to the method, the thought of a greedy algorithm is used for reference, each opportunity is utilized to the greatest extent, namely, in each step of searching, the satellite is utilized most sufficiently to observe the target, so that the target with the minimum window interval is realized, and the utilization rate of satellite observation resources is improved.
本发明公开了一种基于窗口最小间隔的空间目标轮巡任务自主规划方法及系统,该规划方法包括如下步骤:步骤1、将获取的时间窗口集合进行切片,获取时间窗口切片集合,并按照开始时间排序;步骤2、第一轮求解:在满足约束条件的情况下,对于每一颗卫星,以观测窗口间隔最小为任务规划原则,进行快速求解,优先保证每个目标都被观测;步骤3、第二轮求解:可以在步骤2结果的基础上,通过第二轮求解,利用剩余观测资源实现对部分空间目标的重复观测。本发明借鉴了贪婪算法的思想,最大可能地利用每一次机会,即在搜索的每一步,它都将最充分的利用卫星对目标进行观测,从而实现窗口最小间隔的目标,提高了卫星观测资源的利用率。
