An efficient bayesian algorithm for joint target tracking and classification

It is pointed out in this paper that a more appropriate description of the joint target tracking and classification (JTC) problem would be the simultaneous probability density functions (pdfs) of target state, and target class instead of the joint target state-class pdf. In this paper, models of different classes are combined into a unified set. The Bayesian optimal JTC algorithm based on pdfs of target state and target class is derived, which integrates a Bayesian multiple-model filer and a Bayesian classifier. Also given is a suboptimal JTC algorithm with much lesser computational complexity, which is suitable for real-time application. Simulation results reveal that the proposed JTC algorithm provides a theoretically attractive solution to a class of joint target tracking and classification problems.
