The invention provides a trajectory prediction-based dynamic target relay observation task planning method. The method comprises the following steps of: firstly, performing mathematical modeling on dynamic target relay observation task planning; and according to observed target motion information, predicting a moving track of the target after the target is separated from a satellite view field, generating a relay observation task of a next stage according to a track prediction result and a current state of a satellite constellation, and quickly distributing the task to a next satellite by adopting a contract net algorithm to realize relay observation of the dynamic target. According to the invention, the relay observation of the dynamic target is realized, the problem that the relay observation satellite lacks task information guidance when the satellite carries out relay observation on the dynamic target is solved, and the satellite switching frequency in the relay observation process is reduced.

    本发明提供一种基于轨迹预测的动态目标接力观测任务规划方法,首先对动态目标接力观测任务规划进行数学建模。根据观测得到的目标运动信息,对目标脱离卫星视场后的运行轨迹进行预测,并根据轨迹预测结果和卫星星座当前状态生成下一阶段的接力观测任务,并采用合同网算法快速将任务分配到下一颗卫星,实现对动态目标的接力观测。本发明实现对动态目标的接力观测,克服了卫星在对动态目标进行接力观测时,接力观测卫星缺少任务信息引导的问题,减少了接力观测过程中的卫星切换频率。
