摘　　要：通过分析机扫二维相控阵体制雷达的波束扫描特点,明确了雷达资源调度的基本原则和3项核心评价指标。针对低任务载荷和高任务载荷场景分别进行了问题分析和任务调度需求分析,提出了基于任务密度分布的全周期自适应时间缩放、调度周期动态时变以及任务优先级动态调整的组合调度策略,可自动根据任务载荷高低情况进行多任务时序的实时调整以实现评价指标的最优。仿真结果表明该组合调度策略可适应多种任务场景,明显提升时间利用率、波束扫描效率以及任务执行率。By analyzing the beam scanning characteristics of the two-dimensional mechanical scanning phased array radar,the basic principe and three core evaluation indexs of radar resource scheduling are defined.Problem analysis and task scheduling requirement analysis are carried out for low task load and high task load scenarios respectively.A combined scheduling strategy is proposed,which includes full-cycle adaptive time scaling based on task density distribution,dynamic time-varying scheduling cycle and dynamically adjusted task priority.For achieving the optimal evaluation index,the multi-task timing can be adjusted automatically in real time according to the task load level.Simulation results show that the combined scheduling strategy can adapt to various task scenarios and improve time utilization,beam scanning efficiency and task execution rate significantly.
