| 多功能相控阵雷达的任务复杂性和实时性需求不断提高，传统的基于一定驻留周期的任务调度方法不能满足实时切换要求。针对此问题，提出了一种基于脉冲周期的任务切换和实时调度的方法，两级调度器与执行器一体化设计减少任务调度时间开销，综合考虑优先级调度算法和抢占式调度策略确保了任务有效执行，面向任务模型的参数化设计使得任务调度能灵活适应各类作战任务需求。仿真结果表明，此方法能较好地控制高优先级任务丢失率, 获得更高的任务执行有效性。 |

| Abstract: |
| Due to task complexity and real-time performance of multifunction phased array radar, the conventional task scheduling methods based on certain dwell time period are unable to meet the needs of rapid switchover. A real-time task scheduling method is proposed, which can reduce the time overhead of task scheduling by the integrated design of two levels of schedulers and actuators. To ensure the task execution, the priority scheduling algorithm and the preemptive scheduling policy are applied comprehensively. The proposed method can adapt to all kinds of operational mission requirement by using task model parameterized design. Simulation results demonstrate that the proposed method can achieve smaller task drop ratio and higher task effectiveness. |
