Webb25 maj 1990 · Abstract: In this paper we present a data association technique that utilizes the strength of target returns to improve tracking in a cluttered environment. The approach generalizes the Probabilistic Data Association Filter (PDAF) to include the target amplitude, a feature which is available from the detection system that provides … 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…
