An improved combined interacting multiple models probabilistic data association algorithm

Considering the impact of the common measurements for updating the track to improve PDA algorithm, an improved combined interacting multiple models probability data association(IC-IMMPDA) algorithm, combining IMM algorithm with improved PDA algorithm is proposed. The simulation's results show that the new algorithm is not only much better than the combined interacting multiple models probabilistic data association (C-IMMPDA) algorithm, but also keeping small calculation cost in the environment of dense targets.
