Data association in passive acoustic tracking
Charles M. McIntyre, William Roger · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1993
Multitarget, multisensor passive sonar tracing has many similarities to the radar problem. In particular, data association issues are critical to overall system performance when tracking barely detectable acoustic sources in a very cluttered ambient background. The purpose of this paper is to provide an overview of some of the crucial data management issues in passive acoustic tracking for those who are familiar with radar tracking. The problem of associating multiple detections in time to form input sequences to nonlinear target trackers is discussed. The problem of associating these input sequences, or contacts, with particular sources and then assigning the contacts to localization and tracking resources will also be described.
