Abstract

The particle filtering is a promising non-linear filtering, but degeneracy phenomenon is a problem. In this paper, a new particle filter (scale particle filter, SPF) was proposed to overcome the above-mentioned problem. After important sampling step, the particles were classified into two groups according to their particle-weights, and then some candidate particles were generated by the scale mean of the two groups of particles. The optimizing selection of particles was realized based on its own particle-weight so that the better particles were obtained for estimation. Simulation results demonstrate the feasibility of SPF.

Key words： non-linear filtering; particle filter; scale; degeneracy phenomenon
