A Position-First 3D Inversion Method for Tomosar

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Three-dimensional imaging with tomographic SAR is a hot research topic in the field of SAR. The existing methods usually solve the question based on elevation discretization. When the target point has an off-grid deviation, the accuracy will decrease and the number of spurious points will increase.

Dual-Frequency Distributed Compressive Sensing TomoSAR Method for Reducing Flight Requirements

IEEE Geoscience and Remote Sensing Letters
The existing single-frequency tomographic synthetic aperture radar (TomoSAR) 3-D reconstruction method suffers from insufficient observation information due to the high cost and long period of acquisition of the required multi pass data.

Experimental Validation of Compact Tomosar for Vegetation Characterization

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The study aims to explore the potentials of compact TomoSAR for vegetation characterization. The compact mode transmits either in linear or circular polarized waves and receives at horizontal and vertical polarization providing a different perspective to the understanding of the target.

An Adaptive Complex LISTA Network Exploiting Toeplitz Structure for TomoSAR 3D Reconstruction

International Conference on Digital Signal Processing
In the 3D reconstruction of urban areas using TomoSAR, buildings often exhibit significant sparsity in the elevation direction, typically with only 1 to 3 scattering targets.

Feature Design for Classification from Tomosar Data

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
While previous work primarily focused on using Tomographic Synthetic Aperture Radar (TomoSAR) data to analyze the 3D structure of the imaged scene, we study its potential for the generation of semantic land cover maps in a supervised framework. We extract different features from the covariance matrices of a tomographic image stack as well as from the ...

‘Scatter coherence’ suppression for TomoSAR in urban areas

Remote Sensing Letters, 2015
Synthetic aperture radar tomography (TomoSAR) is typically used to retrieve elevation, deformation, and other key information by separating scattering points of the same slant range in multiple baseline SAR images. ‘Scatter coherence’ (SC), which refers to the coherent relationship between scattering points in cells of the same resolution (e.g.

Channel Imbalance Calibration Method for Airborne TomoSAR System

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
Synthetic aperture radar (SAR) tomography (TomoSAR) systems have been widely used because of its capability of 3D reconstruction of urban area. However, due to the critical requirements of phase and amplitude accuracy, the channel imbalance of the airborne multi-baseline TomoSAR system must be estimated and compensated.
