带时间窗的相控阵雷达实时任务调度方法

摘要

In order to solve the traditional phased array radar task scheduling,a prior way,which will ignore the issues of the urgency and importance of task time,based on work style,is adopted to come up with a way of the phased array radar task scheduling that is based on the three characteristic parameters:the priority of itself work style,deadline and idle time. It accommodates the different load conditions of the radar scheduler by adjusting the parameter weight. The request of handling sudden tasks with time windows is aimed at making sure that more and more high priority tasks can be dispatched in a scheduling interval. The simulation results show that the methods mentioned in the article can efficiently increase the successful rate of task scheduling and obviously improve the property of radar scheduler.%为了解决传统相控阵雷达任务调度中采用基于工作方式优先级的方法而存在忽略任务时间紧迫性和重要性的问题，提出了一种基于任务自身工作方式优先级、截止期和空闲时间3个特征参数的相控阵雷达任务调度方法，通过调整参数的权重来适应调度器不同的负载情况，并采用时间窗处理发生冲突的任务请求，确保更多的高优先级任务在调度间隔内被调度。仿真结果表明，所提出的方法能够有效提高任务的调度成功率，明显改善调度器性能。
