Webb7 - Probabilistic data association tutorial. Making an assignment between a single track and a single measurement can be problematic. In the previous tutorials you may have … The Probabilistic Data Association Filter (PDAF) is a statistical approach to the problem of plot association (target-measurement assignment) in a target tracking algorithm. Rather than choosing the most likely assignment of measurements to a target (or declaring the target not detected or a measurement to be a false alarm), the PDAF takes an expected value, which is the minimum mean square error (MMSE) estimate. The PDAF on its own does not confirm nor termi…
