A Study on the Scheduling Method of Rotating Phased Array Radar Based on Dual Adaptive Strategy

针对旋转相控阵雷达任务调度过程中资源利用不充分问题和调度算法优化需求,提出基于双重自适应策略的任务调度算法(TSM-DAS)。首先,通过探究旋转相控阵雷达扫描特性,将雷达任务分为两类;然后,针对不同类型任务的调度时间差异,提出任务调度的双重自适应策略;最后,结合任务时间窗、优先级和贪心算法,给出基于双重自适应策略的任务调度算法,并通过仿真实验对TSM-DAS进行验证。实验结果表明,相比其他同类算法,TSM-DAS能够有效提升雷达资源利用率,降低任务截止期错失率,从整体上提升旋转相控阵雷达的任务调度效能。

As for the problem of the underutilization of resource in task scheduling and the optimize requirement of the scheduling method of rotating phased array radar,a task scheduling method based on dual adaptive strategy(TSM-DAS)is proposed in this paper.Firstly,the scanning characteristics of rotating phased array radar are analyzed.Based on this,the radar tasks are divided into two categories.Then,considering the requirements of scheduling time difference of tasks,a dual adaptive strategy of task scheduling is proposed.At last,the TSM-DAS is proposed by combining the task time windows,the task priority,and the greedy algorithm,and simulation experiments are executed to verify the effectiveness of TSM-DAS.The results show that compared to other algorithms of the same kind,TSM-DAS can greatly increase the radar resource utilization ratio while decreasing the task deadline miss ratio,which overall achieves better resource allocation in the task scheduling of rotating phased array radar.
