Abstract:

In multi-target tracking, aiming at the data association problem and the curse of dimensionality that arises due to the increased size of the state-space associated with multiple targets, a novel algorithm based on the parallel Gaussian particle filter (parallel-GPF) is proposed. By assuming that the states of the targets conditioned on the past measurements are mutually independent, the algorithm is amenable for multi-channel parallel implementation. With the Markov chain Monte Carlo (MCMC) approach the marginal association probabilities can be evaluated. Then, the filtering distributions of each target are computed independently with GPF. And, Quasi Monte Carlo (QMC) integration is utilized for approximating the prediction and update distributions. Finally, the proposed method is applied to passive multi-sensor multi-target tracking. Simulation results show that the proposed algorithm can obtain a better tracking performance than JPDAF, MCMCDAF and MC-JPDAF.
