‘Scatter coherence’ suppression for TomoSAR in urban areas
Remote Sensing Letters, 2015Synthetic 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.

Robust Height Reconstruction of Buildings Based on Esprit-Tomosar
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019TomoSAR is one of the methods which can perform three-dimensional (3-D) imaging with multiple SAR datasets by using Direction-of-Arrival (DOA) estimation techniques to reveal height distribution of scatterers. However, resolution of the TomoSAR is generally insufficient for height estimation of small objects on the ground surface.

Robust TomoSAR focusing for forest height retrieval
2018 IEEE International Conference on Environmental Engineering (EE), 2018This paper aims to discuss and present analysis on robust reconstruction of vertical structure of forested area suing multi-baseline synthetic aperture radar (SAR) data. To deal with problem of low signal to noise (SNR) ratio, robust non-local (NL) techniques of covariance matrix estimation are employed and compared with classical multi-looking ...

A 3D Reconstruction Method of Mountain Areas for TomoSAR
2019 IEEE International Conference on Signal, Information and Data Processing (ICSIDP), 2019Tomographic Synthetic Aperture Radar (TomoSAR) is an advanced technique which allows to achieve 3D reconstruction of interested areas, such as man-made buildings, mountain areas, and other topographic features. However, up to now there exist few researches about 3D reconstruction of mountain areas using TomoSAR.

Tomosar and PS-InSAR analysis of high-rise buildings in Berlin
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012Using high-resolution SAR data stacks, a large amount of persistent scatterers (PS) can be found in urban areas, which are used for very detailed surface deformation monitoring. However, in dense urban areas, many of these points consist of more than one dominant scatterer in elevation direction.

Sparsity based TomoSAR combining CS and GLRT
2018In this paper a new approach to TomoSAR imaging is presented. It is based on the joint use of a Constant False Alarm Rate (CFAR) detection approach of multiple targets and of Compressive Sampling (CS) tomographic reconstructions. CS is widely used to recover a sparse signal but suffers from the presence of outliers.
