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.
