一种基于优先级调度的相控阵机动目标跟踪方法

Approach of tracking maneuvering targets based on priority scheduling for phased array radars

在相控阵雷达跟踪加搜索(TAS)工作方式下,为跟踪较大的机动目标,提出一种目标机动检测器设计方法,得到归一化的目标机动系数.基于该方法,给出了一种动态计算优先级的调度算法,较好地解决了机动多目标跟踪的资源调度问题.与几种常用机动检测器相比较,结果表明了这种机动检测器具有更高的检测概率.最后在多目标环境下进行机动目标跟踪的蒙特卡罗仿真,仿真结果显示了多目标机动检测器和资源调度算法的有效性.

An algorithm for detecting maneuver is presented in order to aceurately track targets with acute maneuver under the track and scan （TAS） mode. Then a scheduling algorithm based on priority calculation dynamically is proposed, which can distribute radar resource suitably among tasks. The algorithm is compared with other kinds of maneuvering detecting algorithms. And the results show that this algorithm has higher detecting probability. Finally, Monte Carlo simulation results show the effectiveness of the proposed approach.
