Sensor and signature research covers surveillance, remote reconnaissance and signature management. The purpose of sensor research is to evaluate, demonstrate and develop new or increased sensor capability in support of defence and security. The research mainly concerns sensor systems in the fields of radar and optics with advanced image and signal processing including data fusion. The applied research in this area is oriented towards experimental work and involves close international collaboration. Sensor systems have to function in an environment of interference and to be able to detect hidden and masked objects. The physical properties of objects in the surroundings and the effects of the atmosphere are therefore important areas for research. With regard to signatures, research activity is oriented towards signature material and signature modelling. Apart from research and development we also undertake application-oriented training.
