- W2018862130 abstract "We simulate observations of geostationary satellites using different optical interferometer array configurations. We test several array designs, including the typical Y shaped array, a couple of circular arrays, telescopes mounted on a linear movable boom, and a couple of arrays of 30 telescopes on a non redundant and a redundant hexagonal grid. We use aperture synthesis techniques to reconstruct images from the simulated observations. We compared the performance and reliability of the different arrays, and find that the image quality increases with the number of telescopes being used. We also find that short baselines, with lengths of ~2m are needed in order to recover the large scale structure of the satellite. Some of the best results are produced by the non redundant and redundant arrays on a hexagonal grid. Considering that the satellite appearance changes with illumination, the boom array is not a good design, since it requires too much time to observe at different angles." @default.
