A Position-First 3D Inversion Method for Tomosar
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Three-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.

3D Reconstruction in Mountain Area for Array TomoSAR
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020Array Tomographic Synthetic Aperture Radar (TomoSAR) is an advanced technique with elevation resolution through acquiring images from different angles. Due to the special single-pass mode, there is no temporal decorrelation caused by revisit time between multiple images.

Model-based polarimetric scattering decomposition for TomoSAR
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017SAR Tomography, or TomoSAR, is one of the powerful SAR data analysis tool with multi-baseline data set, especially for height estimation of scattering centers. On the other hand, PolSAR, or Polarimetric SAR, is also powerful tool for scattering characteristic discrimination of terrain. Several PolSAR analyses have applied to the TomoSAR.

Feature Design for Classification from Tomosar Data
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018While 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 ...

Experimental Validation of Compact Tomosar for Vegetation Characterization
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018The 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.

Channel Imbalance Calibration Method for Airborne TomoSAR System
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020Synthetic 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.

Tomosar Focusing by Means of A Variant of Tikhonov Regularized Method
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Tomographic synthetic aperture radar (TomoSAR) imaging has shown great potential in the three dimensional SAR focusing in recent years. One practical challenge is that the spatial separation of the multi-pass system is always nonuniform and also the number of tracks is very limited, thus leading to the focusing results inaccurate. Conventional Tikhonov

TomoSAR Application for Early Warning in Infrastructure Health Monitoring
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Earth observation using spaceborne sensors with short revisiting time has forgone the limits of conventional assessment methods. In this paper, we investigate the use of SAR Tomography (TomoSAR) to monitor infrastructures, using Morandi Bridge in Genoa, Italy, as a case study.
