The author discusses how helicopters may fly autonomously using fuzzy logic, without crashing too often. He reviewes the added value of sensor fusion in military observation systems. Sensor fusion is motivated by the expected qualitative and quantitative improvement of observations and thus of situation …

The author illustrates how partial and soft decisions are aggregated via non-linear schemes. Fuzzy logic is used to formally describe sensor fusion. Although intuitively appealing, one may conclude that data fusion has not yet brought about the expected breakthrough. Several explanations for this can …

The authors discuss the need for a C4I architecture for the Netherlands armed forces and list the progress that has been made up to now. Several challenges are identified, such as unique real-time requirements, interoperability and agility and unique security requirements.

In this paper the authors describe the iTasks workflow system. The iTasks system is a software library written in the declarative programming language Clean, which allows for the highlevel specification of multi-user workflows. An important advantage of the iTasks system above commercially available …

In this issue, the members of the Combat Systems Department inform the defence community and (military) research institutes about their current and future research projects. The contributions cover a large part of the field of technological academic research that military organisations require

Orienting paper about kinetic non-lethal weapons. One of its purposes is to help the non-specialist reader better understand scientific and technological aspects of these new weapon systems. Physical parameters and experimental methods are reviewed. Performance tests of two existing non-lethal weapon …

This paper describes research into generic sensor management principles that enable the development of a support system that is capable of bridging the growing gap between the available knowledge and the required sensor management related knowledge

This paper discusses the principle of geoacoustic inversion. That will demonstrate the need for validation with experimental data. The RNLNC has been involved in two recent sea trials that will be described in brief. Results for the geoacoustic parameter characterization for typical examples will be …

The author investigates how acoustic information about the seabed can be obtained from bottom-reflected shipping noise. An innovative idea is the use of sound sources of opportunity. When expeditionary forces enter shallow or confined waters, the environment has a great influence on the performance of …

It is well-known that instead of changing course exactly at the edge, changing course when the sweep radius reaches the edge (i.e. changing course at distance R from the edge) generally yields higher probabilities of detection. In this article the authors shall investigate whether or not an even higher …
