Chapter 15 Multitarget Multisensor Tracking

Multitarget-Multisensor tracking is a category of widely used techniques that are applicable to fields like air traffic control, air/ground/maritime surveillance, transportation, video monitoring and biomedical imaging/signal processing. In this chapter, various multitarget-multisensor tracking algorithms to handle state estimation, data association, track initialization, spatial clutter intensity estimation, debaising, and multisensor fusion in centralized/distributed/decentralized architecture are discussed in detail, including their quantitative and qualitative merits. In addition, several evaluation metrics are presented to measure the performance of different multitarget-multisensor tracking systems. Various combinations of these algorithms and performance evaluation metrics will provide a complete tracking and fusion framework for multisensor networks with application to civilian as well as military problems. The application of some of these algorithms and performance evaluation metrics is demonstrated on a representative real scenario, where several closely spaced targets are tracked using a radar system.
