The Swedish armed forces are being more and more oriented towards international operations. This implies that the signature solutions of Swedish equipment must be adapted to international environments. The purpose of this preliminary study is to determine the need for information, knowledge and development of new methods for signature management for international operations. The report contains a review of the conditions for signature management (environment, weather, sensor threat and background) and how they can be characterized. Then the different steps for signature work are described: measurements, modeling, analysis and finally the design of the low signature solutions. The report concludes with a proposal for future work.
