摘　　要：基于多星联合侦察的卫星数传调度问题是研究如何为卫星数传任务中每个单数传任务分配地面资源及数传时间的问题,对该问题的模型进行了研究.首先建立了单数传任务模型及卫星数传任务模型;然后在此基础上建立了问题的约束满足优化模型,重点分析了问题的目标函数及主要约束条件;为了解决该问题,最后提出了一个基于双综合优先度的启发式调度算法,并通过实例验证了算法的有效性.研究成果实现了问题的形式化描述,并给出了一种有效的问题求解算法.Satellite data transmission scheduling problem based on multi-satellite combined reconnais- sance is such a problem that studies how to assign ground resources and data transmitting time for every single data transmission task belonged to satellite data transmission task. A study of the problem＇s model was made. To this problem, the models of single data transmission task and satellite data transmission task were construc- ted firstly. Based on these models, the model of this problem was constructed, and the object function and main constraints were analyzed especially. For solving the problem, a heuristic scheduling algorithm named double complex priority algorithm （DCPA） was presented and validated by an example lastly. The studying results realize formalizing description of the problem, and give a valid solving algorithm for it.
