The research area Sensors and Signatures focuses mainly on electromagnetic and optical sensors for surveillance and reconnaissance, as well as on signature management.

The aim of the sensor research is to assess, demonstrate, and develop new or enhanced sensor capabilities. Sensor systems, consisting of sensors and advanced signal and image analysis, are studied primarily in the radar and optical domains.

In the signature field, the work focuses on monitoring developments in materials and techniques for signature management, that is, how objects can be adapted to a changing background, on modelling the signatures of different objects, and on signature-management measures for platforms and units.

The main clients are the Swedish Armed Forces and the Swedish Defence Materiel Administration (FMV). Applications for civil defence include the surveillance and protection of critical infrastructure, with clients including, among others, the Swedish Police Authority.
