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 in which the goal is to localize macroporosities inside a rubble-pile near-earth asteroid with two small spacecraft carrying a bistatic radar.
