Fusing Landsat and SAR data for mapping tropical deforestation through machine learning classification and the PVts-ß non-seasonal detection approach
(2021-07-26)
Article
Accés obertThis article focuses on mapping tropical deforestation using time series and machine learning algorithms. Before detecting changes in the time series, we reduced seasonality using Photosynthetic Vegetation (PV) index ... -
Generation of precise wide-area geocoded elevation models with ERS SAR data
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertThe authors present an improved technique for the generation of digital elevation models (DEM), capable of dealing with full scene images (100×100 km) coming from an interferogram obtained with ERS satellite data. Starting ... -
Interferometric SAR signal analysis in the presence of squint
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertIn the following paper an analysis of the SAR impulse response signal from the interferometric point of view is expounded, with the intention of studying its phase behaviour in the presence of high squint values. The work ... -
SAR interferometric coherence in wide band systems
(VSP BV, 2000-02-28)
Article
Accés obertThis paper presents a study of the interferometric coherence aimed to the understanding of the main sources of phase error of an operative wide band system. This objective is accomplished by finding a theoretical expression ... -
Sparsity-based radar imaging of building structures
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, we address imaging of the interior structure of a building using a reduced number of measurements in through-the-wall imaging and urban sensing applications. Unlike majority of the feature detection methods ... -
Spherical wave near-field imaging and radar cross-section measurement
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-05-31)
Article
Accés obertThe paper presents a new inverse synthetic aperture radar (ISAR) algorithm intended for radar cross-section (RCS) imaging and measurement from scattered fields. The method, based on a spherical-wave near-field illumination ... -
Study of structural elements in heritage buildings with ground penetrating radar images
(2018)
Comunicació de congrés
Accés obertMaintenance and repairing or ancient buildings requires efforts and a wide knowledge of the structures. However, in many cases, the constructive methods, the distribution of supporting elements and the materials are unknown. ...
