Blackboard Architectures for Sonar Data Association
Semi-automated systems are being developed to aid naval command teams in building undersea warfare (USW) tactical pictures representing the surface and subsurface environment and containing information regarding the number of detected targets, target identities, and target positions, courses, and speeds. The fusion of multiple acoustic data sources, as well as the incorporation of supporting information from non-acoustic data sources, is recognised as a key requirement for achieving accurate and efficient USW tactical picture compilation. This paper provides an overview of work conducted at the Defence Research Establishment Atlantic (DREA) on the application of the blackboard architecture, a software architecture for distributed problem solving, to sonar data association, a specific aspect of sonar data fusion involving the association of multiple acoustic signals corresponding to a given platform.
