Abstract : 　The track association and fusion technique of synchronized multi2sensor tracking system in case of correlated noises is developed. The discretization to linear continuous time system expresses that there exists a correlation among common process noise and measurement noise ,although they are independent of in linear continuous time system. And then in the light of hypothesis testing theory ,the synchronized multi2sensor track association and fusion algorithm is presented. The simulation results express its validity.
Key words : 　correlated noise ;target tracking ;association fusion
