Trajectory Information Exchange Multi-Bernoulli Filtering for Track-Before-Detect

This paper presents the extension of the track-before-detect based Information Exchange Multi-Bernoulli (IEMB) filter for estimating the set of alive trajectories. We present the filtering recursion, which propagates a multi-Bernoulli density for the set of alive trajectories, and propose a Gaussian implementation based upon the Iterated Posterior Linearisation filter (IPLF). We present simulation results which demonstrate the superior tracking performance of the Trajectory IEMB when compared to a sequential track-building approach using the IEMB filter for sets of targets.
