摘　　要：针对空间探测相控阵雷达系统,提出了一种观测任务规划算法。首先,建立了观测任务模型和观测任务资源占用模型;其次提出一种多任务并行截止期越早越优先(multi-task parallel earliest deadline first,MTPEDF)调度算法来解决观测任务规划,该算法综合考虑雷达的搜索任务与跟踪任务来进行系统资源的分配。对于跟踪任务,算法结合目标的过境时间以及当前系统的负载情况,以此来确定雷达对该目标的观测时间段;最后给出了算法的评估方法。利用在轨的2 886个空间目标进行仿真验证,仿真结果表明算法可以较好地利用系统时间资源,合理安排雷达观测任务。A novel mission planning algorithm for space surveillance phased array radar systems is presented. Firstly, the model of the observation mission and its resource consumption is analyzed. And then a MTPEDF scheduling algorithm for observation mission planning is proposed. The algorithm takes the search missions and track missions into account synthetically for allocating radar resource, and for the track missions it can calculate the reasonable observation time based on the target crossing time and the radar load. Finally, two parameters are given for evaluating the mission planning algorithm. Using the real data of 2 886 space targets, simulation results show that the algorithm can rationally plan radar observation missions and utilize the system resources effectively.
