C4ISR - Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance

Effective systems for acquiring and managing information are essential for both military defence capability and civil crisis management. The Division of C4ISR – Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance – focuses on providing sensor operators and commanders with reliable information to increase their situational awareness and facilitate the decision-making process. Our research ranges from sensors for data acquisition to information fusion and decision support.

Sensor systems that can monitor scenarios as they unfold, detect abnormal events and recognize objects can provide early warnings about unusual or hostile activities and help assess a complex situation correctly and timely. The systems often need to work in a variety of challenging conditions – adverse weather, poor lighting, over long distances and with limited power. In military contexts, tactical requirements regarding covertness, robustness to jamming and protection of own systems against various threats add to the complexity. In-depth knowledge about the signatures of own military units as perceived by different sensors is therefore important for taking efficient measures to increase the survivability in hostile environments. Moreover, modern command and control systems, connected to various information sources and other systems, require careful analysis and management of cyber threats and IT security risks. Finally, what eventually determines the practical effectiveness of technical support systems is how their functionalities balance the capabilities of the humans involved.

The research at C4ISR addresses emerging sensor technologies, such as radar, laser, hyperspectral, microwave and thermal imaging devices, as enablers for new capabilities, and how established devices can be used more efficiently and in new ways to increase their operational value. In many cases, advanced signal processing is the key to better performance, cost-effective solutions and new military and civil applications. Furthermore, C4ISR develop tools, techniques and methods for radio communication, electronic warfare, positioning, cyber security and human-machine interaction. Our research and development work is pursued in a systematic manner to leverage important findings and translate research results into enhanced operational capacity.
