摘要

ABSTRACT OF THE DISCLOSURE A MANEUVERING TARGET TRACKING METHOD VIA MODIFYING THE INTERACTING MULTIPLE MODEL (IMM) AND THE INTERACTING ACCELERATION COMPENSATION (IAC) ALGORITHMS5 The present invention relates to the field of target tracking and more generally to a method employing improved algorithms, which achieve excellent tracking performance for a high-g maneuvering target. The two-model Interacting Multiple Model algorithm and the Interacting Acceleration Compensation algorithm will be modified by introducing adaptive factors through the detection of the normalized innnovation squaredwhich is chi-square probability distributed. The implementation results show that the modified algorithms can handle the target sudden maneuver better and are more accurate than the original algorithms.
