Outliers Improvement Based on the Strong Tracking Filter
Xu Yu · Modern Radar · 2003
Because of both errors in extraction of radar information and communication, the radar measurements received from radar stations often contain outliers .The influence of outliers on the Kalman filter for target tracking is analyzed in this paper, and a new tracking algorithm based on the strong tracking filter with fault-tolerant strategy is suggested. This new algorithm can not only sufficiently absorb good innovations to increase filtering precision but also efficiently restrain bad influence coming from outliers. Simulation suppress show that the modified filtering algorithms are practical and efficiently resistant to outliers in measurements data..
