摘　　要：对多个动目标持续跟踪成像是高轨遥感卫星的重要任务之一。为此,文章提出了高轨遥感卫星对多个动目标持续跟踪的任务规划方法。以卫星姿态机动次数和姿态机动角最小为优化目标,以卫星对动目标持续跟踪的起始、终端状态、服务次数约束及时间分配的限制为约束,建立高轨遥感卫星姿态机动对多个动目标的调度模型。在此基础上,采用遗传算法生成高轨遥感卫星在每个任务周期对多个动目标调度的任务序列,结合九宫格跟踪算法完成对多个动目标的持续跟踪。仿真结果表明:任务规划方法可以成功对1个高速动目标及多个中低速动目标进行跟踪监视,具有很好的适应性。The observation and tracking of moving multi-targets is one of the important tasks of high-orbit remote sensing satellites.A mission planning method is proposed for high-altitude remote sensing satellite cameras for moving multi-targets tracking.With the optimization of the time and angle of satellite attitude maneuvers,a constraint model based on satellite attitude maneuver,terminal state,service times and time allocation constraints is established.On this basis,the genetic algorithm is used to generate the task sequence of the high-orbit remote sensing satellite scheduling moving multi-targets in each task cycle,and the nine-grid tracking algorithm is used to accomplish continuous tracking of moving multi-targets.Simulation results show that the proposed method has good adaptability to monitoring and tracking a high-speed moving target and multiple medium-low-speed moving targets.
