Publikováno v:
Earth and Space Science, Vol 10, Iss 4, Pp n/a-n/a (2023)
Abstract This article presents a novel 3‐D shape reconstruction strategy for small solar system bodies using spaceborne radar which is applied in flyby trajectories to characterize multiple targets in one mission to save time and cost. In this stud
