ISAR Imaging Of Satellites In Space – Simulations And Measurements

Kurzfassung

The Microwaves and Radar Institute of German Aerospace Center (DLR) has developed and constructed an experimental radar system called IoSiS (Imaging of Satellites in Space), being presently still in the commissioning phase. The overall goal of that system is research on concepts for advanced acquisition of high-resolution radar images of objects in a low earth orbit (LEO). In addition for performance estimation a software tool was implemented including relevant parts of the imaging system. Using that tool the hardware setup is optimized in parallel during development and construction. This paper outlines the comparison between simulation results and the obtained measurement results of real space objects. Further on a simulation result is discussed showing an interferometric image of a satellite obtained by a suggested bi-static satellite imaging system.
