A Modified Maneuvering Target Model and Adaptive Filtering Algorithm

Based on Current Statistical Model for target tracking,a modified maneuvering target model and adaptive filtering algorithm is presented by modifying the probability distribution of maneuvering acceleration and the relation between maneuvering acceleration and its covariance and the covariance matrix of process noise.The theoretic analyses and simulation results show that this modified model can characterize all kinds of maneuvering motion of target and that the adaptive tracking algorithm has good performance.So it is worthy to be applied widely in practice.
