Radar Systems
The Armed Forces’ command and control systems must be able to exercise surveillance over large areas and to detect all types of target 24 hours a day regardless of weather.
In the Department for Radar Systems FOI has long experience in research and development of long range radar surveillance and reconnaissance systems.
We primarily work with low frequency synthetic aperture radar (SAR) for wide-area ground surveillance, distributed airspace surveillance in networks, system utilisation of digital array antenna technology, and wideband multifunction systems. System design, signal processing, scattering phenomenology and verifying experimental work are major parts of the research.
FOI’s Department for Radar Systems is engaged in problem-oriented work ranging from theory and studies to the building of experimental systems. These systems are used for research both in the laboratory and in field trials under realistic conditions both in Sweden and in international cooperation. The CARABAS-II SAR system, operating in the VHF band, is a unique tool for providing information on concealed stationary ground targets under foliage or camouflage. The new LORA system, operating in the UHF band, also has the capability of moving target detection. The systems are used as a generic research tools both in military and civil applications such as forest mapping.
The Swedish Armed Forces and the Defence Materiel Administration (FMV) are our largest customers. We also collaborate with the Swedish defence industry, principally with Ericsson Microwave Systems AB and we have a close cooperation with several Swedish universities and foreign research agencies.
