Abstract:

When tracking multi-maneuvering targets with jump Markov system generalized labeled multi-Bernoulli filter, there are too many motion mode hypotheses that need to be calculated and pruned frequently, which may increase the computational complexity and negatively affect the tracking accuracy. In order to solve the problem, an interacting multiple model (IMM) based grouping δ-generalized labeled multi-Bernoulli filter is proposed. With this filter, all tracks fall into different groups, association mapping and hypothesis weight calculation run in each individual group, which reduces the computational complexity and enables parallelization. Moreover, IMM algorithm is incorporated into this filter to deal with target maneuver. The time prediction and data update equations are given in detail. Simulation results show that the proposed filter can track multiple maneuvering targets with higher accuracy and lower computational cost.

Key words: random finite set (RFS), δ-generalized labeled multi-Bernoulli (δ-GLMB) filter, multi target tracking (MTT), interacting multiple mode (IMM)
