Abstract An Enhanced Multiple Model Particle Filter(EMMPF) algorithm is presented for maneuvering target tracking. Rather than allocating the particles to the various modes according to mode probabilities as the MMPF, the new algorithm proposes an approach which enables the user to control the number of particles in a certain mode flexibly without interaction between particles of different mode. The estimations of mode and state are calculated respectively, and the posterior probability of each model is updated with the model likelihood function. It is demonstrated that the new algorithm can achieve better performance with less particles, compared with MMPF.
