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他波束的发射期或接收期。仿真结果表明,相比于原有的动态优先级算法,所提算法的调度成功率提升了25%,时间利用率提升了35%,执行威胁率提升了25%。Aiming at the subjective time resource allocation and the low time resource utility in the air defense phased array radar, after considering the task internal structure, a novel online interleaving algorithm is proposed. On the basis of setting the task importance and the urgency into dynamic priorities, the algorithm can execute other task transmitting durations and receiving durations in the task waiting durations under the time and energy resource constraints. The simulations show that, compared with the former dynamic priority scheduling algorithm, the proposed algorithm improves the successful scheduling ratio by 25%, the time utilization ratio by 35%, and the treat ratio of execution by 25%.
