相控阵波束驻留调度综合优先级构造方法

A Synthetic Priority Construction Method for Phased Array Radar with Adaptive Dwell Scheduling Algorithm

在相控阵雷达自适应波束驻留调度算法中,任务的优先级设定是关键。文中提出一种新型综合优先级构造方法,该方法将任务的工作方式优先级、截止期和目标威胁度作为确定综合优先级的影响因素,利用二维优先级表思想,采用两级非线性加权方法构造综合优先级。仿真结果表明:在相控阵雷达自适应波束驻留调度算法中,提出的新综合优先级构造方法相较于现有的综合优先级构造方法,降低了跟踪任务丢失率,提高了实现价值率和修正价值率。

In adaptive dwell scheduling algorithms for phased array radar, the priority setting of tasks is the key. A new synthetic priority construction method is put forward in this paper. In this method, task priority, target threat degree and task deadline are regarded as the influencing factors for the synthetic priority, and two-dimensional priority table with two-stage nonlinear weighted method is used to construct synthetic priority. Compared with other existing synthetic priority construction methods in adaptive dwell scheduling algorithms for phased array radar, simulation results show that the tracking task drop ratio can be reduced, the hit value ratio and modified hit value ratio can be improved in the new synthetic priority construction method.
