Research of PF Based on D-S theory Algorithm

The application of Particle Filter needs no rigorous precondition, moreover Particle Filter demonstrates good convergence. But Particle Filter has inherence shortcomings, which limit its further application. An new improved Particle Filter is proposed. In the paper, the thought and difficulty for improvement is explained. Then viewpoint to solve the difficulty is introduced with D-S theory. After introducing D-S theory, paper gives then method of overcoming degradation of samples with D-S theory. The simulation result show that the thought is right, the method is feasible, the result is effective.
