Synthetic Aperture Radar Interferometry Based on Vortex Electromagnetic Waves
IEEE Access, 2019 The vortex electromagnetic (EM) wave carrying orbital angular momentum (OAM) offers a new degree of freedom for synthetic aperture radar (SAR) imaging. Because vortex EM waves have helical wavefronts, the vortex EM wave-based SAR echo contains the three ...
