Digital beamforming for near-space wide-swath SAR imaging

Abstract

Inspired by recent advances in near-space technology and synthetic aperture radar (SAR) technique, this paper presents one digital beamforming-based near-space wide-swath imaging technique. Near-space defined as the space region between 20 km and 100 km, which is above storms and not constrained by orbital mechanics like satellite or high fuel consumption… (More)
