摘要:

针对无源定位跟踪中野值的出现会降低滤波的可靠性和稳定性问题,结合新息似然的概念提出了一种基于似然的野值检测与剔除方法。通过计算卡尔曼滤波更新中得到的似然值,设定门限,以达到野值的检测与剔除的目的。仿真结果表明,该算法有效地处理了野值对定位跟踪精度的影响,使得目标定位跟踪精度有了较大的提高。

Abstract:

In passive locating and tracking system, the emergence of outlier has a bad influence in both the stability and the precision of the filtering. In order to solve this problem, a method for the outlier detection and elimination based the conception of innovation likelihood is proposed. Given a threshold, the innovation likelihood is calculated in the update of the Kalman filter to aim at the detection and elimination of the outlier. The proposed algorithm plays a good performance in passive locating and tracking system with outlier.

Key words: locating and tracking;outlier;innovation likelihood;kalman filter
