DRDC Valcartier has initiated, through a PRECARN partnership project, the development of an advanced simulation testbed for the evaluation of the effectiveness of Network Enabled Operations in a coastal large volume surveillance situation. The main focus of this testbed is to study concepts like distributed information fusion, dynamic resources and networks configuration management, and self synchronising units and agents. This article presents the requirements, design and first implementation builds, and reports on some preliminary results. The testbed allows to model distributed nodes performing information fusion, dynamic resource management planning and scheduling, as well as configuration management, given multiple constraints on the resources and their communications networks. Two situations are simulated: cooperative and non-cooperative target search. A cooperative surface target behaves in ways to be detected (and rescued), while an elusive target attempts to avoid detection. The current simulation consists of a networked set of surveillance assets including aircraft (UAVs, helicopters, maritime patrol aircraft), and ships. These assets have electrooptical and infrared sensors, scanning and imaging radar capabilities. Since full data sharing over datalinks is not feasible, own-platform data fusion must be simulated to evaluate implementation and performance of distributed information fusion. A special emphasis is put on higher-level fusion concepts using knowledge-based rules, with level 1 fusion already providing tracks. Surveillance platform behavior is also simulated in order to evaluate different dynamic resource management algorithms. Additionally, communication networks are modeled to simulate different information exchange concepts. The testbed allows the evaluation of a range of control strategies from independent platform search, through various levels of platform collaboration, up to a centralized control of search platforms.
