UAVSAR Tomography for Vertical Profile Generation of Tropical Forest of Mondah National Park, Gabon
Earth and Space Science, Volume 7, Issue 10, October 2020., 2020 Abstract Polarimetric synthetic‐aperture radar (SAR) remote sensing has been widely used for structural and biophysical parameters retrieval of forest vegetation. It has been found that the combination of polarimetric properties and interferometric characteristics of SAR remote sensing provides the capacity to retrieve forest height.

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-

RECONSTRUCTION OF BUILDING FOOTPRINTS USING SPACEBORNE TOMOSAR POINT CLOUDS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 This paper presents an approach that automatically (but parametrically) reconstructs 2-D/3-D building footprints using 3-D synthetic aperture radar (SAR) tomography (TomoSAR) point clouds.

TerraSAR‐X StripMap Data Interpretation of Complex Urban Scenarios with 3D SAR Tomography
Journal of Sensors, Volume 2014, Issue 1, 2014., 2014 The severe layover problem of complex urban scenarios in SAR data makes SAR data interpretation very difficult, especially for nonexperts. In this paper, we use 3D SAR tomography for SAR data interpretation of dense urban areas. An efficient and robust approach named Butterworth‐filter based singular value decomposition (BSVD) is used for tomographic ...

Sparse Scenario Imaging for Active Radar in the Forward‐Looking Direction
Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 The resolution of multiple targets at the same range cell but different angles in the forward‐looking direction is of great trouble for active radar. Based on compressive sensing (CS) framework, a sparse scenario imaging approach using joint angle‐Doppler representation basis is proposed, which employs multisensor and single‐receiver channel hardware ...
