摘　　要：为解决应急条件下卫星对地观测任务时间紧迫的问题,从卫星执行对地观测任务的全过程出发,提出了卫星对地观测任务全周期规划模型,综合考虑卫星完成任务的各个阶段,缩短整个任务的执行时间,使其满足应急条件下的时间需求。采用启发式算法求解,并研究了基于冲突队列的解的调整优化策略。实验验证所提的模型和算法能够较好地解决卫星对地观测任务规划问题,在时间紧迫的条件下与传统的各阶段的独立任务规划相比,能够提高任务的完成率,具有实际的应用价值。To solve the satellite observation planning problem for emergency tasks with timing limits, the process of satellite observation is analyzed, and a whole cycle mission planning model on satellite observation is proposed. The model integrates four phases of satellite observation, to satisfy the timing limits of satellite observation missions in emergency. A heuristic algorithm was suggested to solve the model, and an optimization adjustment strategy based on conflict queue was also proposed. Simulation results show that the model and algorithm are feasible for mission planning of satellite observation, and improving the mission accomplishment ratio of independent mission planning for each phase.
