摘　　要：针对多星协同观测问题,现有的研究均以地面目标可被卫星观测到为规划结束条件,而随着遥感数据应用的不断深入,产生了一种考虑连续观测时长的周期轮巡需求。对任务的时间窗进行预处理以划分周期频次,将问题简化为在每个频次内实现对地目标的连续观测。在预处理基础上,设计了连续观测时间窗生成算法(Generation of Continuous Observation Time Windows Algorithm,GCOTWA),将每个频次内的时间窗进行拼接以实现对地面目标的连续观测,并设计了3个启发式因子以计算连续观测时间窗的优先级。仿真试验的结果充分验证了GCOTWA的可行性和有效性。To solve the problem of multi-satellite cooperative observation,the existing studies all take the ground targets that can be observed by satellites as the planning end condition.However,with the further application of remote sensing data,there is a need for periodic observation which considering duration of the continuous observation.Firstly,the task is preprocessed to divide the cycle,and the problem is simplified to achieve the continuous observation of the ground target in each cycle.Then,the Generation of Continuous Observation Time Windows Algorithm(GCOTWA)is designed on the basis of pretreatment,and the time window in each frequency is spliced to achieve continuous observation of ground targets.Afterwards,three heuristic factors are designed to calculate the priority of the continuous observation time windows.Finally,the simulation results fully verify the feasibility and effectiveness of the GCOTWA method.
