基于目标威胁度的相控阵雷达自适应调度方法

对时间资源的合理安排是相控阵雷达发挥自身优势的关键。将目标威胁度引入调度算法中,与工作方式和任务截止期共同进行综合优先级规划。通过构建目标威胁度的量化模型,使雷达在调度跟踪任务时依目标威胁度大小分配时间。提出了修正价值率和执行威胁率的概念,完善了性能评估指标。通过仿真,全面评价了新算法性能,验证了引入目标威胁度的合理性。结果表明,新算法可以有效提升相控阵雷达对高威胁度目标的处理能力。

Adaptive Scheduling Algorithm Based on Threat Level of Target for Phased Array Radars

The arrangements to time resource account most for the phased array radar to optimise its superiority. The threat level of targets is introduced into scheduling algorithm,to form the comprehensive priority function with the working patterns and the deadline of tasks. Through structuring the qualification model of the threat level of targets,the phased array radar will arrange time successively according to it when scheduling tracking tasks. The conception of modified high value ratio and the threat ratio of execution are presented,improving the evaluation index. In simulation,the new algorithm is evaluated roundly,and the validity of the algorithm and the improved performance for high threat level of target of radar are proved by the results.
