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

The proposed joint-symbol MLSE receiver employs another delay interferometer (DI) based on cross polarization interference together with a traditional DI to mitigate PMD impairment to phase-shift keying. Applied to an 80-Gbit/s DQPSK demonstration sy
