The term “Flexible Association / ID-Aided Tracking” (FA/IDAT) refers to a novel approach to data fusion in which kinematic and non-kinematic data are maintained in separate data structures. In comparison with traditional data fusion systems, FA/IDAT is less vulnerable to errors in data association, because of its ability to represent situations that are not easily represented in a traditional data fusion system. In particular, FA/IDAT allows the existence of a known entity to be asserted without committing that identity to a particular associated kinematic track. The representation of such a situation is more natural in FA/IDAT than in Multi-Hypothesis Tracking (MHT). Thus, FA/IDAT has the potential to achieve the benefits of MHT with far less computational load. In the form in which it was first introduced, the FA/IDAT algorithm lacked the capability to deal with false alarms and missed detections. Such a capability has now been added. This document presents the current state of development of the FA/IDAT algorithm, points out several areas where further development is required, and discusses the relationship between FA/IDAT and MHT.
