| 摘 要： | 针对视距（line-of-sight, LOS）和非视距(none-line-of-sight, NLOS)混合环境的定位跟踪问题, 提出一种基于扩展H∞滤波（EHF）和扩展卡尔曼滤波(EKF)的交互式多模型(IMM)定位跟踪算法。目标与基站之间的LOS、NLOS传输信道分别用EKF和EHF匹配, 模型间的转换用马尔可夫过程进行描述。Monte Carlo仿真结果表明, 该算法具有较高的定位精度、较好的跟踪稳定性, 且计算时间与基于EKF的IMM算法相当, 具有较好的可实现性。

| Abstract: | To attack the location and tracking problem in LOS/NLOS hybrid environment, this paper proposed a robust interactive multiple model approach based on extended H-infinity filter (EHF) and extended Kalman filter (EKF). It matched the LOS and NLOS transmission channels between the base station and target by EKF and EHF, respectively. Then, it described the mode transmission between EKF and EHF by a Markov process. Monte Carlo simulation results show that the algorithm has higher positioning accuracy, better tracking stability and similar computing complex compared with the interactive multiple model method based on EKF. |
