Abstract
This article investigates beamforming limitations in a distributed antenna aperture aboard a Low Earth Orbit (LEO) satellite, focusing on platform displacement effects. While a larger aperture supports dense coverage via narrow beams, structural micromovements distort the radiation pattern. A fully digital beamforming approach using null placement is explored, but applying precoding at platform and intra-platform levels reveals performance constraints. The study outlines these limitations and highlights potential directions for future research to enhance system robustness.
