This report is a short account of the activities, outputs etc, of the radar signature project in the years 2001-2003. For more detailed information about the activities we refer to the various issued reports and memos. The main goal of the project has been to develop new and improved modelling methods for radar cross section calculations. The work has been supported with measurements at the FOI site at Lilla Gåra. An important focus for the project has been to develop modelling methods which take into account the interaction of the radar waves with the ground and targets. This interaction can give a significant contribution to the total radar cross section of a ground object. To be able to model this contribution, knowledge is needed of how different ground types scatter the radar wave in different directions and at different frequencies - one thus has to determine the so-called bistatic scattering matrix. In order to validate the modelling methods, carefully controlled measurements are needed. The project has therefore in 2003 produced the basis for a new measurement facility - the so-called "bistatic measurement arch" - which has been designed and manufactured in the FOI workshop. It is now to be found at Lilla Gåra and preliminary bistatic measurements have already been carried out. In 2003 a three-year CEPA-project was initiated (Swe, Spa, Eng, Ger, Ita) where members of the radar signature project are taking part. Sweden chairs the project, with Jonas Rahm as chairman. The project aims at a basic understanding of the target-background interaction.
