Abstract:

In order to overcome the choice of the importance function and the sample impoverishment after resampling, an improved particle filter algorithm based on evolution fission is presented. The algorithm uses the UKF to generate the importance function and updates the samples based on evolution fission, which could increase the diversity of the samples and overcome the degeneration of the typical particle filter. Simulation results prove that the presented algorithm has a high tracking accuracy and a good tracking performance compared to the typical particle filter.

Key words: particle filter, resampling, the importance proposal distribution, evolution fission, unscented particle filter(UKF)
