Abstract:

In the process of multi-sensor target information fusion, a consistent distributed information filtering algorithm is proposed to improve the high dependence and low stability of the centralized filtering algorithm on the fusion center in the target tracking state estimation.The algorithm is based on the state information and measurement information of each sensor itself and neighbor nodes to achieve real-time tracking and positioning of the target, and each node is a data processing center, which solves the problem of insufficient anti-damage capacity of the fusion center and ensures that when some sensor nodes have problems, the global task can be carried out smoothly. Simulation analysis shows that the consistency distributed filtering algorithm can solve the problem of multi-sensor target tracking information fusion, and its accuracy is higher than that of a single sensor, and tends to be the accuracy of multi-sensor centralized information filtering, which can be applied to nonlinear system tracking with high stability and reliability.

Key words: consensus-based distributed filtering, target tracking, centralized information filtering, information fusion, multi-sensor

摘要:

在多传感器目标信息融合过程中,提出一种一致性分布式信息滤波算法,用于改善集中式滤波算法在目标跟踪状态估计中对融合中心依赖度高,稳定性低的问题。该算法是根据各个传感器自身以及邻居节点的状态信息和量测信息,实现对目标的实时跟踪定位,每个节点都是数据处理中心,解决了融合中心抗毁伤能力不足的问题,保证部分传感器节点出现问题时,全局的任务能够顺利进行。仿真分析可得,运用一致性分布式滤波算法,可以解决多传感器目标跟踪信息融合问题,其精度高于单一传感器滤波精度,且趋于多传感器集中式信息滤波的精度,可应用于高稳定性、可靠性的非线性系统跟踪。
