Abstract :
In target tracking system, the measurement and the true state of target are nonlinear. Particle filter can deal with nonlinear and nonGaussian filtering. The crucial technique of particle filter is the selection of proposal function. In this paper is presented the particle filter-BLUE_PF, which is based on BLUE measurement conversion to get the proposal function. The state estimation and its covariance, which are derived from BLUE measurement conversion, can be used to determine the proposal function. The simulation results show that BLUE_PF has superiority to EKF_PF and UKF_PF.
