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。
研究瞭分佈式無源多傳感器繫統多目標跟蹤問題,在隻有測嚮信息可以利用的情況下,分佈式繫統首先利用波門技術分彆對各箇無源傳感器角度測量數據進行關聯配對和濾波;然後,將處理結果送到融閤中心,在融閤中心通過構造的χ2分佈檢驗統計量進行多目標方位航跡的關聯;最後,通過交扠定位和位置信息融閤穫得多箇目標的位置信息估計,實現無源多目標跟蹤。論文通過倣真分析對算法的有效性和可行性進行瞭驗證。

Multiple targets tracking algorithm of distributed The bearing measurements were selected through validation passive sensor system was studied in this paper. 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.
