摘要: 研究基于反馈的雷达和红外分布式航迹融合.首先给出雷达和红外传感器多目标跟踪算法以及融合中心航迹融合算法,然后将融合状态一步预测及其协方差阵反馈到局部传感器形成新的跟踪门,并把此跟踪门和未反馈前的跟踪门的交集作为下一步估计的有效跟踪门.对不能融合的航迹,给出了目标指示.最后对所提算法进行了计算机仿真研究.Abstract: Radar and IR distributed track fusion based on the feedback is studied . Firstly,multiple target tracking algorithm for every local sensor and fusion center target track fusion algorithm are put forward. Secondly,one-step fusion predictions of target states along with covariance matrix are fed back to local sensors to form a new tracking gate for each target,and the intersection of the new tracking gate and the original gate formed before feedback is taken as the effective tracking gate. In addition,target ...
