Modified input estimation with interacting fading memory for maneuvering target tracking

An improvement on the modified input estimation (MIE) is proposed for maneuvering target tracking. With the advantage of reduced sensitivity to modeling errors, a set of fading memory is selected to indicate different maneuver level. The proposed method jumps between these different fading memories according to a Markov chain. Experimental results show that the presented method has more efficiency in tracking a maneuvering target than the MIE with conventional fading memory and the simple MIE.
