The Electro-Optical Signal Transmission and Ranging (EOSTAR) model is an image-based Tactical Decision Aid (TDA) for thermal imaging systems (MWIR/LWIR) developed for a sea environment with an extensive atmosphere model. The Triangle Orientation Discrimination (TOD) Target Acquisition model calculates the sensor and signal processing effects on...

A long term field trial called FESTER (First European South African Transmission Experiment) has been conducted by an international collaboration of research organizations during the course of almost one year at False Bay, South Africa. Main objectives of the experiment are a better insight into atmospherical effects on propagation of optical...

Most models that predict the infrared signature of an object are based on steady-state equilibrium conditions and do not model the dynamic nature of the real world. To gain more understanding of the dynamic infrared signatures of an object, several outdoor experiments were performed, using a CUBI and a small vessel as an object. Dynamic changes...

An overview is given of the First European - South African Transmission ExpeRiment (FESTER), which took place in South Africa, over the False Bay area, centered around Simon's Town. The experiment lasted from April 2015 through February 2016 and involved continuous observations as well as periodic observations that took place during four...

Looking through the atmosphere, it is sometimes difficult to see the details of an object. Effects like scintillation and blur are the cause of these difficulties. Exhaust plumes of e.g. a ship can cause extreme scintillation and blur, making it even harder to see the details of what lies behind the plume. Exhaust plumes come in different shapes...

The EOSTAR model aims at assessing the performance of electro-optical (EO) sensors deployed in a maritime surface scenario, by providing operational performance measures (such as detection ranges) and synthetic images. The target library of EOSTAR includes larger surface vessels, for which the exhaust plume may constitute a significant signature...

In general, long range visual detection, recognition and identification are hampered by turbulence caused by atmospheric conditions. Much research has been devoted to the field of turbulence compensation. One of the main advantages of turbulence compensation is that it enables visual identification over larger distances. In many (military)...

Infrared imagery over long ranges is hampered by atmospheric turbulence effects, leading to spatial resolutions worse than expected by a diffraction limited sensor system. This diminishes the recognition range and it is therefore important to compensate visual degradation due to atmospheric turbulence. The amount of turbulence is spatially...

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...

A commercial long-range scintillometer was deployed over a 2-km path in False Bay, South Africa, for a timeframe of one year. The turbulence data retrieved from the instrument are compared to turbulence parameters inferred from micrometeorological data and models, and the relation between experimental and model-data is explored.

Atmospheric turbulence can cause severe blurring and scintillation in images. These distortions result in less detailed images. Using only image enhancement techniques can improve the quality of the images to some extend, but usually not enough to see all details. Turbulence correction techniques, such as post-processing techniques using a...

Once a crime has been perpetrated, forensic traces will only be persevered in the crime scene for a limited time frame. It is therefore necessary to record a crime scene meticulously. Usually, photographs and/or videos are taken at the scene to document it, so that later on one will know the exact place of an object. Another possibility is to...

This paper gives an overview of research at TNO in the field of maritime situational awareness (MSA). Our expertise on radar, sonar, electro-optics, electronic support measures and tracking/fusion is typically employed for vessel detection and vessel anomaly detection. Illustrative examples of these applications are presented addressing the...

Research fields such as Network Enabled Capabilities, ubiquitous computing and distributed sensor networks, etc. deal with a lot of information and a lot of different processes to fuse data to a desired level of situation awareness. Already quite some research is done in applying information theoretic concepts to sensor management. Effective...

Sensor systems need to be more adaptive to perform well in dynamically changing environments. Common awareness in sensor systems enables distributed agents to perform coordinated actions and reason about other agents. In addition, physical distribution of the agents in the network prevent a single point of failure and provides distributed...
