Abstract
Most asteroids subtend extremely small angles in the sky so it is impossible to directly discern either surface reflectivity, shape variations, or the spin axis using existing ground-based telescope systems. A super-resolution inversion technique relates the lightcurves of a rotating asteroid, which is represented as a polyhedron with planar surface facets, to the unknown radial vertex distances. Any number of lightcurves at different aspect angles can be incorporated into the formalism. Generalizations to delay-Doppler echo radar imaging are also discussed, as well as some of the issues associated with these inversion methods.
