RM-CSTV: An effective high-resolution method of non-line-of-sight millimeter-wave radar 3-D imaging
National Science OpenNon-line-of-sight (NLOS) imaging is a novel radar sensing technology that enables the reconstruction of hidden targets. However, it may suffer from synthetic aperture length reduction caused by ambient occlusion. In this study, a complex total variation (

High-resolution High-dimensional Imaging of Urban Building Based on GaoFen-3 SAR Data
Leida xuebao, 2022 Conventional Synthetic Aperture Radar (SAR) can only obtain two-dimensional (2-D) azimuth-range images without accurately reflecting the three-Dimensional (3-D) scattering structure information of the targets. However, SAR Tomography (TomoSAR) is a multi-
