The paper develops an information fusion system that aims at supporting a commander's decision making by providing an assessment of threat, that is an estimate of the extent to which an enemy platform poses a threat based on evidence about its intent and capability. Threat is modelled in the framework of the valuation-based system (VBS), by a network of entities and relationships between them. The...
Sensor resource management (or process refinement) is a element of any information fusion system. Common level 4 sensor management (SM) inter-relations to level 1 target tracking and identification have been developed in the literature. During Fusion06, a panel discussion was held to explore the challenges and issues pertaining to the interaction between SM and situation and threat assessment. This...
In order to manage situations efficiently, commanders need to be aware of possible future events that might occur. They also need to be aware of the relative probabilities of different events, so that they know which events to take into account when making plans of their own. In this paper, we describe a concept prototype that was developed at FOI during 2006 that helps commanders do these tasks....
A technique is proposed to extract system requirements for a maritime area surveillance system, based on an activity recognition framework originally intended for the characterisation, prediction and recognition of intentional actions for threat recognition. To illustrate its utility, a single use case is used in conjunction with the framework to solicit surveillance system requirements.
Since its conception the JDL model has provided the fusion community with a way to describe and understand various activities in the data fusion community. As the community continues to make great strides and advancements, primarily in the Level 2/3 arena, a greater understanding is coming about. As a result it is time to revisit the model and to incorporate these lessons learned. In this paper we...
