Abstract:

To address the target tracking problem of unknown heavy-tailed noise statistical characteristics, the trajectory Poisson multi-Bernoulli mixture filtering (TPMBM) algorithm based on Gamma student’s t-distribution inverse Wishar is proposed. The algorithm uses student’s t-distribution and inverse Wishart distribution to model the extended state of noise and extended target, and embeds multivariate multiple filter (MMF) into the TPMBM filter to estimate innovative characteristics, adaptively adjusts the noise degree of freedom and scale matrix. Multi window fusion technology is used to further improve the adaptive estimation ability of MMF. The simulation results demonstrate that, compared with existing algorithms, the proposed algorithm exhibits the best performance in tracking accuracy, centroid error, and intersection over union (IOU) shape fitting. The proposed algorithm reduces the centroid error by 15% and improves the IOU shape fitting by 10%. It also demonstrates higher estimation accuracy and robustness in the influence of noise in heavy-tailed noise environments.

Key words: heavy-tail noise, student’s t-distribution, extended target tracking, trajectory Poisson multi-Bernoulli mixture (TPMBM) filtering
