Multipath Reflectivity Estimation in Urban Environments for Synthetic Aperture Radar Images [PDF]

, 2010
Synthetic Aperture Radar (SAR) images a target region reflectivity function in the multi-dimensional spatial domain of range and cross-range. SAR synthesizes a large aperture radar in order to achieve a finer azimuth resolution than the one provided by ...

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 ...
