Mitigating Ill-Posedness in SAR Ionospheric Tomography Toward Multisatellite Collaboration
In recent years, spaceborne low-frequency fully polarimetric synthetic aperture radar (PolSAR) ionospheric tomography has been an emerging technology for 3-D ionospheric computerized tomography (CIT). However, conventional single-satellite SAR (e.g., PALSAR) tomography suffers from pronounced ill-posedness due to restr...
