分布式无源传感器系统多目标跟踪算法

Multi Target Tracking Algorithm of Distributed Passive Sensor System

摘要:

研究了分布式无源多传感器系统多目标跟踪问题,在只有测向信息可以利用的情况下,分布式系统首先利用波门技术分别对各个无源传感器角度测量数据进行关联配对和滤波；然后,将处理结果送到融合中心,在融合中心通过构造的χ2分布检验统计量进行多目标方位航迹的关联；最后,通过交叉定位和位置信息融合获得多个目标的位置信息估计,实现无源多目标跟踪。论文通过仿真分析对算法的有效性和可行性进行了验证。

Abstract:

Multiple targets tracking algorithm of distributed passive sensor system was studied in this paper. The bearing measurements were selected through validation region, and those in the validation region were associated. The bearing tracks were associated in the data fusion center through chi-square test. The direction finding location algorithm and position data fusion problem were discussed in this paper. Simulation results showed that using the method proposed in this paper the targets could be tracked with bearing-only measurements, and the feasibility and validity of the algorithm was revealed.
