In Multipath assisted Indoor Navigation and Tracking (MINT), individual Multi-Path Components (MPCs) of the Ultra WideBand (UWB) channel needs to be extracted. A sequential Monte-Carlo based implementation of the multi-source multi-target Probability Hypothesis Density (PHD) filter is used in order to jointly estimate the number of multipath components present as well as their individual parameters. The PHD-Filter is able to model the changing visibility of individual multipath components along a measurement trajectory. As the PHD-Filter does not maintain target track continuity, a path-labelling method is used.
