Wide area radar networks with data persistence

For most of its existence, radar has been a tool for real-time observation and processing. Indeed, most signal processing aspects of radar analysis were concerned with real-time detection, filtering, clutter rejection, tracking and targeting. This paper outlines the application of radar in a networked environment, which becomes much more than a real-time feed-forward system. It incorporates many and varied aspects of signal and information processing, from tracking and fusion, through to statistical analysis and data mining. These networks have been deployed and are operating in different fields of application, and some of these real-world examples will be presented herein.
