Introduction This paper addresses the need for improved sensors for mine clearance operations and humanitarian demining efforts. These operations require an information system that is capable of supporting activities such as planning, training, simulation, execution, documentation and assessment. To achieve this goal the system is best implemented using a service-based architecture, with sensors and other sources feeding into a common database that is capable of fusing the diverse information and users being able to request tailored and specific information in various formats and through a multitude of communication channels and operator interfaces. Figure 1. The 3d-Radar system has been developed for research purposes at the Norwegian University of Science and Technology. Currently the system is being exploited for applications in the commercial and military/public market. In a Network Centric Concept the sensor systems need to be able to comply with the specific requirements of precision, flexibility and mobility . The first of these issues may directly be associated with image resolution and accurate geo-referencing of radar data. It also implicit that
