In practice, Multisensor systems use dissimilar sensors having different data rates. Such sensors may also have inherent delays as well as communication delays. Recently the authors developed a track fusion algorithm that attempted to account for realistic constraints of sensor fusion. The objective of this paper are two folds. First, it shows that the synchronous track fusion problem can be derived as a special case of the developed track fusion algorithm. Second, using simulated target tracks, the performance of the asynchronous track fusion (ASTF) algorithm is analyzed and compared to an existing fusion algorithm. Different sensor data rates and communication delays are used in the simulations.
