广域动目标监视模式是借助天线在方位向上快速扫描来实现大范围动目标监视的一种雷达工作模式，这使得雷达系统可以对同一个动目标在不同时刻进行多次观测并跟踪其轨迹。该文提出了一种基于机载广域监视雷达系统的地面目标动目标跟踪方法。首先，根据动目标检测得到的信息估计运动目标的位置；然后对每个目标设置关联门限，并对进入门限的目标计算加权的关联度；最后通过全局最优得到关联的结果。该文还比较分析并确定了算法对误差大小的适用范围。通过仿真并与另外两种算法进行比较，验证了该算法的有效性，实际数据的处理结果也说明了算法的可行性。

Wide Area Surveillance Ground Moving Target Indication mode is an important mode in surveillance radar systems since it can monitor extensive area in a short time, which enables moving target tracking. A method for tracking ground moving targets based on airborne wide-area surveillance radar system is proposed in this paper. First, the location of the moving targets is estimate according to the moving target information obtained from the detection process. Then a correlation threshold is selected for each target to decide which one would compute weighted relate-rate. Finally, the global optimal relevance is computed. This paper analyzes the applicable error scope of the method. The algorithm is compared with another two methods in the simulation and proved to be effective. Moreover real data results demonstrate the feasibility of the proposed method.
