The ability to track targets is essential in many applications. Well-established military applications include missile defense and battle field situational awareness. Civilian applications are ever-growing, ranging from traditional applications such as air traffic control and building surveillance to emerging applications like supply chain management and wildlife tracking. In all of these applications, target tracking addresses the problem of combining sensed data and target history to provide accurate and timely knowledge of the location of one or more moving objects. Current technology has enabled the development of sensor networks, distributed ad-hoc networks of hundreds or thousands of nodes, each capable of sensing, processing and communication.
