摘　　要：针对目前分布式航迹融合算法中鲁棒性和实时性问题,基于充分利用多传感器测量数据中互补和冗余信息的思想,通过局部航迹估计间模糊支持度函数的建立和支持度矩阵的求解,动态地实现各局部航迹估计在融合中心权重的合理分配,进而提出了一种基于动态加权的分布式多传感器航迹融合算法。最后,通过蒙特卡罗仿真验证了该算法的有效性。Through the analysis of the robust and real-time property in the distributed track fusion algorithm at present, a distributed multi-sensor track fusion algorithm based on dynamic weight is given, On the basis of the thought of sufficiently make use of the information of redundancy and supplement with multi-sensor measure data, This algorithm firstly defines a fuzzy support degree function on the local track estimation and establishes support degree matrix, and that utilizes the solving of the matrix to reasonable and dynamic allot the weight coefficient of the local track estimation in the fusion center. Finally, the Monte- Carlo simulation shows the efficiency of this algorithm,
