A Single-Pass Multistatic SAR Satellites Formation Design Method for TomoSAR Data Acquisition

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic aperture radar tomography (TomoSAR) enables 3-D SAR imaging. However, most spaceborne TomoSAR data are currently acquired through repeated passes of a single satellite, during which the atmospheric and deformation phases complicate processing ...

Three-Dimensional Reconstruction of Partially Coherent Scatterers Using Iterative Sub-Network Generation Method

Remote Sensing
Synthetic aperture radar tomography (TomoSAR) has gained significant attention for three-dimensional (3D) imaging in urban environments. A notable limitation of traditional TomoSAR approaches is their primary focus on persistent scatterers (PSs ...

STAMI: A machine learning-based small-scale tomography-aided multibaseline (Pol)InSAR forest height inversion framework

International Journal of Applied Earth Observations and Geoinformation
The complementary measurements of model-based multibaseline (polarimetric) synthetic aperture radar interferometry ((Pol)InSAR) and data-driven SAR tomography (TomoSAR) have become the development trend of forest height mapping missions.

Sparse Matching Filtering Algorithm for Tomographic SAR Imaging

Leida xuebao
Synthetic Aperture Radar Tomography (TomoSAR) has emerged as the primary technique for generating 3D SAR point clouds. In practice, ignoring the quadratic phase distribution in the elevation dimension causes defocusing artifacts due to inherent Fresnel ...

3-D Joint Inversion of Urban Persistent and Distributed Scatterers via SAR Tomography

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Existing urban spaceborne synthetic aperture radar (SAR) tomography (TomoSAR) inversion methods predominantly focus on persistent scatterer (PS), while distributed scatterer (DS) constitute a substantial proportion of urban targets and provide critical ...
