Abstract:

Aiming at the low tracking performance of the Gaussian mixture(GM)variational Bayesian-δ-generalized labeled multi-Bernoulli (VB-δ-GLMB) filtering algorithm in nonlinear scenes, a maneuvering multi-target tracking algorithm is proposed, which combined with the iterative optimization based on proximal point algorithm (PPA) and (variational Bayesian, VB) approximate and cubature Kalman filter (CKF), to suit for nonlinear models. Based on GM-VB-δ-GLMB, the proposed algorithm uses inverse Gamma (IG) and Gaussian product mixture distribution to approximate the joint posterior density of the measurement noise covariance and state. Then, PPA-CKF-VB (PCKF-VB) method is used to predict and update the Gaussian term parameters in the transfer process. Finally, smoothing of variational Bayesian cubature Rauch-Tung-Striebel (VB-CRTS) is utilized to improve the filtering accuracy. Simulation results indicate that the target tracking accuracy of the proposed algorithm is obviously improved compared with the existing VB-δ-GLMB algorithm for the nonlinear system with unknown measurement noise.
