| 摘 要： | 讨论了密集目标环境下跟踪门门限对多目标跟踪系统性能的影响。在略去杂波的情况下,以方差压缩比作为跟踪系统性能的衡量指标,对跟踪门性能进行了理论分析。给出了矩形跟踪门配合K alm an滤波算法和PDA关联算法的仿真数据。提出了一种跟踪门门限的选取方法,将离线仿真得到的门限直接应用于跟踪系统,门限计算复杂减小,适用于对速度要求较高的跟踪系统。

| Abstract: | In this paper,influence of sizes of tracking gates on MTT systems in the dense targets environment is discussed,ignoring the influence of noise points,and the performance of the tracking gate is analyzed by using the covariance ratio as the index.The rectangular gate with the Kalman filter and PDA(association) algorithm is emulated.This paper also presents how to decide the size of the tracking gate in the dense environment.As the complexity of the computation is reduced,the algorithm can be used in high speed tracking systems. |
