摘　　要：针对防空相控阵雷达中时间资源分配主观性强、利用率低的问题,结合任务内部结构,提出一种新的在线交错调度算法.该算法在将任务的重要性和紧急性均置于动态优先级的基础上,使得雷达任务收、发波束之间的等待期可以用来执行其它任务的发射期或接收期.仿真结果表明,相比于任务模式优先级加截止期的调度算法,所提算法的调度成功率、时间利用率和执行威胁率均得到有效提升.Aiming at the subjectivity of the time resource allocation and the low utility of the time resource in the air defense phased array radar,a novel online task interleaving scheduling algorithm was proposed by considering the internal structure of the task. On the basis of setting the importance and the urgency of the task into dynamic priorities, the algorithm can execute other task＇s transmitting period or receiving period during the task waiting period. The simulations show that the proposed algorithm significantly improves the successful scheduling ratio, the time utilization ratio, and the treat ratio of execution compared with the highest task mode priority and earliest deadline first（ HPEDF） algorithm.
