摘要
为研究只测向目标跟踪系统在观测噪声为ε污染高斯分布背景下的辐射源机动目标鲁棒跟踪问题,提出一种简易而有效的变结构鲁棒跟踪算法.该算法由机动目标快速鲁棒检测器、变结构跟踪器(鲁棒MGEKF/PLKF)以及系统误差补偿等环节组成,能够在ε污染高斯分布背景下快速鲁棒检测和跟踪辐射源机动目标,同时根据系统误差特征可实时补偿系统跟踪误差.仿真结果表明,该算法能够有效解决辐射源机动目标鲁棒跟踪问题.
The Bearing -Only Target tracking problem is a general problem for the target tracking in passive localization system. However, the robust target tracking of maneuvering emitter on the background of ε contaminated Gaussian distribution have been an unsolved problem in the field of BOT system. A simple and effective method is proposed on the base of a variable structure robust target tracking algorithm, which is composed of a fast robust detector of maneuvering target, a variable structure tracking system （ robust MGEKF/ PLKF） , and a system of complementation of system error. This algorithm can implement a fast robust detection and tracking of the maneuvering source target on the background of ~ contaminated Gaussian distribution, and can complement the system tracking error on real time based on the error characteristics. The simulation result shows that this method can resolve the problem of the robust tracking of maneuvering source target, and have an significant effectiveness.
