针对协方差控制的策略不满足雷达跟踪目标的实时性要求,文中采用协方差和目标威胁度联合控制的方法来研究关于相控阵雷达波束调度的问题,建立相控阵雷达波束分配的最优化模型。该模型利用目标的运动状态信息,包括目标距离、目标径向速度、加速度和航向,利用层次分析法确定目标威胁度,然后与目标跟踪协方差相结合进一步确定目标优先级,实现目标动态的搜索加跟踪模式(TAS)的波束调度。将该算法与传统的顺序波束调度方法进行比较,仿真结果表明该算法具有较高的时间利用效率,同时也具有较好跟踪性能。

Because covariance control strategy cannot meet the real-time requirements of tracking target for phased array radars, this paper uses the methods of combining covariance and target threat degree to study the issue of beam steering. An optimal model of beam scheduling is established. The model utilizes the information of target motion state, including the distance of target, the target radial velocity, acceleration and direction, to determine the target threat degree by analytic hierarchy process, and then combines with target tracking covariance, further determines the priority of targets, to achieve the adaptive beam scheduling in the dynamic search and track mode (TAS). Comparing the proposed algorithm with the traditional beam scheduling method , the simulation results show that this algorithm can not only have higher time efficiency, but also have a good tracking performance.
