数字阵列雷达波束驻留调度间隔分析算法

针对数字阵列雷达波束驻留调度问题,研究了基于调度间隔分析的调度算法。该算法综合分析了1个调度间隔内申请执行的波束驻留任务,且调度过程中进行了脉冲交错。调度准则充分考虑了任务的工作方式优先级和截止期,并以任务丢失率、实现价值率、系统时间利用率作为评估指标。仿真结果表明修正截止期准则主要强调任务的紧迫性,修正工作方式优先级主要强调任务的重要性,而截止期—工作方式优先级和工作方式—截止期调度准则可以在二者间更好地折中,在总体性能上要优于其他调度准则。

Dwell scheduling algorithm based on analyzing scheduling interval for digital array radar

Aiming at the problem of beam-dwell scheduling for digital array radar,the algorithm based on analyzing scheduling interval was studied.This algorithm analyzed the dwells applied to be executed in one scheduling interval and introduced pulse interleaving.The scheduling criterion took both priorities and deadlines into account fully,with the Task Drop Ratio,Hit Value Ratio,Time Utilization Ratio as evaluation indexes.The simulation results showed that the modified deadline criterion mainly emphasized the urg...
