Far-Field Inversion for the Deep Interior Scanning CubeSat
IEEE Transactions on Aerospace and Electronic Systems(2017)
摘要
This study aims at advancing mathematical and computational techniques for reconstructing the interior structure of a small solar system body via computed radar tomography (CRT). We introduce a far-field model for full-wave CRT and validate it numerically for an orbiting distance of 5 km using a synthetic three-dimensional target asteroid and sparse limited-angle data. As a potential future application of the proposed method, we consider the deep interior scanning CubeSat concept inwhich the goal is to localizemacroporosities inside a rubble-pile near-earth asteroid with two small spacecraft carrying a bistatic radar.
