The Control System of a Distributed Aperture Imaging Testbed

WebThe focus of this feasibility study is on a moderate size three-dimensional satellite constellation operating as a coherent large aperture synthesis array. This aperture synthesis array would consist of 5 to 50 antennas (satellites) having a maximum separation of 100 km. This study considers the main aspects of such a distributed system in more ... WebAperture Synthesis with a Non-Regular Distribution of Interferometer Baselines. Högbom, J. A. In high-resolution radio interferometry it is often impossible for practical reasons to arrange for the measured baselines to be regularly distributed. The standard Fourier inversion methods may then produce maps which are seriously confused by the ... inghams prospectus
