Present-day naval operations take place in coastal environments as well as narrow straits all over the world. Coastal environments around the world are exhibiting a number of threats to naval forces. In particular, a large number of asymmetric threats can be present in environments with cluttered backgrounds as well as rapidly varying...

The traditional approach to maritime operations in open ocean conditions (‘blue waters’) is platform centric. In this approach, an environmental picture is generated on each platform separately. High quality tracks can be made available to other platforms through classic data links, e.g. Link 11 and 16. In case of maritime operations in littoral...

This paper describes the design, implementation and results of a novel probabilistic collision warning system. To obtain reliable results for risk estimation, preprocessing sensor data is essential. The work described herein presents all the necessary preprocessing steps such as filtering, sensor fusion and target tracking. Risk estimation can...

To effectively protect against threats on compounds or other forms of bases, decisions have to be made about follow-up actions. Without appropriate situation awareness threats cannot be timely recognised, so that decisions to contribute to the level of protection cannot be made in time. For acquiring this situation awareness the environment has...

In this paper we have analyzed military and security requirements for surveillance. Using a data-set of wide swath SAR imagery for the English channel and high resolution SAR data for the Zeebrugge and Rotterdam harbour we have discussed if these requirements can be met by using this kind of data. The requirement to detect anomalous behaviour at...

An architecture for a distributed and adaptive multi-sensor fusion engine is described. The engine is developed to improve the protection of European armed forces against the threats troops are facing in urban environments. In particular, the engine needs to be scalable, flexible to quickly adjust to different missions and mission goals, easily...

This paper proposes a human-centered approach to Dynamic Position-ing systems which combines multiple technologies in an intelligent operator sup-port system (IOSS). IOSS allows the operator to be roaming and do other tasks in quiet conditions. When conditions become more demanding, the IOSS calls the operator to return to his bridge position....

The Anglova scenario was developed as part of the NATO IST-124 Research Task Group on Improving Connectivity and Network Efficiency in Heterogeneous Tactical Networks. Since then, it has been successfully used to conduct emulation-based experimentation by multiple groups. This paper describes extensions to the Anglova scenario for the purpose of...

In this paper, a collision warning application is described. The collision warning application is in particular useful when the driver’s view is blocked due to a large vehicle. The risk estimation algorithm, which is originally designed and validated in scenarios with vulnerable road users, is here applied in a non-line-of-sight scenario with...

Under the ESA study contract NR 9837/92/NL/GS synergy in the modelling of microwave will optical remote sensing data has been studied for agricultural crops. One of the most important issues is whether we could expect synergy from various remote sensing sources for crop yield prediction. Crop yield can be predicted already at an early stage of...

This paper describes how cognitive modeling can be exploited in the design of software agents that support naval training sessions. The architecture, specifications, and embedding of the cognitive agent in a simulation environment are described. Subsequently, the agent's functioning was evaluated in complex, real life training situations for...

Although ever more and powerful information collection, processing, storage, and communication devices are available, disadvantaged battlefield connectivity currently prevents full exploitation of the potentially available information. An infrastructure for adaptive information processing and distribution may improve this situation by providing...

Naval ships have camera systems available to assist in performing their operational tasks. Some include automatic detection and tracking, assisting an operator by keeping a ship in view or by keeping collected information about ships. Tracking errors limit the use of camera information. When keeping a ship in view, an operator has to re-Target a...

Throughout the last 40 years, the security breach caused by human error is often disregarded. To relief the latter problem, this article introduces a new class of biometrics that is founded on processing physiological personal features, as opposed to physical and behavioral features. After an introduction on authentication, physiological signals...

Innovation based on open data lags behind the high expectations of policy makers. Hence, open data researchers have investigated the barriers of open data publication and adoption. This paper contributes to this literature by taking a capabilities perspective on how successful open data re-users create value out of the available data sources....

Reliable applications of affective brain-computer interfaces (aBCI) in realistic, multi-modal environments require a detailed understanding of the processes involved in emotions. To explore the modalityspecific nature of affective responses, we studied neurophysiological responses (i.e., EEG) of 24 participants during visual, auditory, and...

We have studied remote sensing data from sensors in different wavelength regions (optical, thermal infrared and microwave) and from different platforms (airborne and spaceborne) in order to extract geographical information. By comparing the extracted information with an existing geographical database ofa test area in the Netherlands we find that...

We have studied an optimal target detection procedure for polarimetric SAR data by using PHARUS data collected during the MIMEX campaign. The detection method is especially suitable when no a priory knowledge of the target is available. We have found that polarimetric whitening filtering preceding an order-statistics CFAR detector gives the best...

In present-day military security operations threats are more difficult to reveal than in conventional warfare theatres, since they take place during the course of normal life. These maritime missions often take place in littoral environments, where acts of piracy, drug trafficking and other threatening events become obscured in the crowd of...
