Today, available radar instruments cannot be applied for flight guidance purposes due to lack of resolution and ground elevation information. On the other side, optical sensors such as infrared systems provide an excellent resolution but are nearly blind at adverse weather conditions such as fog and rain. A new radar technology called ROSAR (Synthetic Aperture Radar based on ROtating antennas) promises to overcome the deficiencies of the traditional radar systems. On the basis of encouraging research work on ROSAR-technology and an investigation of the feasibility of a piloting system based on these ideas, Eurocopter Deutschland and Deutsche Aerospace started a development program called HeliRadar to develop a ROSAR-based piloting system. This device should be able to provide photolike images even under extreme visibility conditions. Details on the investigation and the resulting concepts for synthetic vision based flight guidance at Eurocopter will be given. Following an introduction to the basics of ROSAR-technology, the technical concept of HeliRadar will be presented. The paper concludes with a discussion of the perspectives for civil and military applications.
