The formalization of network centric warfare (NCW) signaled a new Department of Defense drive towards systems that could conceivably interact towards the accomplishment of a common goal. But the debate regarding NCW possibilities and practicalities in terms of existing and potential technologies highlight that much work is needed before the theortical NCW can be realized. The Information and Cyberwarfare...
The contemporary operating environment (COE) imposes significant challenges for military personnel and systems. The asymmetric nature of the threat and the proliferation of sophisticated weapon systems to rogue nations and trans-national terrorist organizations only further the need to ensure friendly forces maintain a high-level of warfighter readiness. As this threat evolves the importance of higher-level...
Intent inference involves analyzing the actions and activities of a target of interest to deduce its purpose. In an environment cluttered with many targets, loaded with information, and under stress, the human may not be able to perform well Hence a cognitive aid that could derive possible intent inference and monitor the target may help augment human cognition and assist critical human decision making...
This paper discusses the application of holonic control paradigm to sensor management in military surveillance operations. Sensor management is described both as part of the data fusion process and as a control problem. The choice of holonic control as the most adequate architecture for sensor management in the military environment is explained and its application to surveillance operations illustrated...
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...
Summary form only given. The routing and munitions management of multiple formations of unmanned combat aerial vehicles (UCAVs) through network enabled sensing will be discussed. The ability of the UCAVs to group into large formations and to divide into smaller formations on their way to high-value, tactical targets will be cast in the optimization. To solve such problem a sensory information management...
Intelligence in the asymmetric environment appears to lend itself to relying more heavily on information coming from human sources which may provide a wealth of opportunistic intelligence. This kind of information is increasingly available in very large quantities and various formats. The intelligence community has the challenge of ensuring that this collected information/knowledge, which is, by its...
We describe data fusion technology relevant to two applications of potential benefit to the Canadian army. The first application is a local situational awareness system (LSAS) while the second is a versatile surveillance platform. The LSAS improves an armored vehicle crew's ability to recognize and locate threats and hazards without leaving the relative safety of their vehicle. It is designed primarily...
Over-the-horizon (OTH) radar and automatic identification system (AIS) are commonly used in the surveillance of maritime areas. This paper presents a method, which includes tracking and association algorithms, for fusing the information from these two types of systems into an overall maritime picture. Data to be fused consists of asynchronous track estimates from the OTH system and measurements obtained...
The international defense and security community is moving ahead at flank speed to realize the vision of network centric warfare (NCW; aka network-enabled capability (NEC) and etc). Extensive efforts are being put forth to define, design, and develop many of the technical components of such a capability, to include varieties of networked communications systems, various highly-capable military platforms,...
In today's fast paced military operational environment, vast amounts of information must be sorted out and fused not only to allow commanders to make situation assessments, but also to support the generation of hypotheses about enemy force disposition and enemy intent. An automation methodology and support tools are required to allow commanders to model and assess dynamic situations such as the behavior...
In this paper, a goal-driven net-enabled distributed data fusion system is described for CanCoastWatch (CCW) project. Multiple sensors are deployed and managed to achieve the goals of situation assessment using a net-enabled architecture. The local tracks reported by multiple sensors are first integrated into global tracks. Decision making is then performed on basic sub-goals that can be directly...
Providing commanders with advanced decision aids requires a good understanding of the processes involved, their information requirements, and the development of formal domain models upon which reasoning processes can be based. Ontologies, as formal domain models, constitute a key component to provide a shared understanding of a domain, and have received increasing interest for the building of advanced...
Defence R&D Canada has been studying the military applications of hyperspectral imagery for a number of years. In other unrelated efforts, the Canadian remote sensing community has also been active in developing hyperspectral algorithms for civilian use. This civilian technology has many potential military applications. In an effort to demonstrate the potential of these defence and civilian technologies...
Defence Research and Development Canada at Valcartier is pursuing the exploration of situation analysis concepts and the prototyping of computer-based decision support systems to maintain the state of situational awareness for the decision maker. The integration of the human element at the beginning of the analysis process is an important facet of our approach. The mathematical formalism and methodology...
By observing various battlefield situations as they unfold and by interacting with peers and with battlefield artifacts, such as sensors and information processing systems, intelligence analysts form internal, mental models of things that they are observing and with which they are interacting. These models provide predictive and explanatory power for understanding a specific situation at hand, for...
A very short overview is given on experience gained in the area of high level information fusion (JDL level 2 and 3) since 1988. The main characteristics of the referenced projects and experimental systems for the support of intelligence officers in land battle missions will be outlined. The different approaches to analyse and model military intelligence processing and the development of concepts...
Summary form only given. Despite significant recent progress in automatic target exploitation (ATE) and recognition (ATR), current ATE systems do not meet the requirements of modern battlefield environments. Next generation ATE systems must actively manage sensor resources, aggregate sensed information across multiple platforms and diverse signaling modalities, and adapt to increasingly agile adversaries...
