SAR interferometric coherence in wide band systems
Sagués Piella, Lluís; Bara Iniesta, Marc Antoni; Fabregas Canovas, Francisco Javier; Broquetas Ibars, Antoni (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 ... -
SAR interferometric phase statistics in wavelet domain
López Martínez, Carlos; Fabregas Canovas, Francisco Javier (2002-09-30)
Article
Accés obertSynthetic aperture radar (SAR) interferometry is employed to obtain topographic information. Owing to noise, interferometric information has to be filtered. The wavelet transform can be employed to filter the interferometric ... -
Single-pass polarimetric SAR interferometry for vessel classification
Margarit Martín, Gerard; Mallorquí Franquet, Jordi Joan; Fabregas Canovas, Francisco Javier (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-11-30)
Article
Accés obertThis paper presents a novel method for vessel classification based on single-pass polarimetric synthetic aperture radar (SAR) interferometry. It has been developed according to recent ship scattering studies that show that ... -
Study of the speckle noise effects over the eigen decomposition of polarimetric SAR data: a review
López Martínez, Carlos; Alonso González, Alberto; Fabregas Canovas, Francisco Javier (European Space Agency (ESA), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper is focused on considering the effects of speckle noise on the eigen decomposition of the co- herency matrix. Based on a perturbation analysis of the matrix, it is possible to obtain an analytical expression ... -
Target spinor calibration (TSC) for polarimetric radar cross-section measurements
Fabregas Canovas, Francisco Javier; Romeu Robert, Jordi; Broquetas Ibars, Antoni; Jofre Roca, Lluís (IEE-INST ELEC ENG, 1995-09-01)
Article
Accés obertA new polarimetric calibration method is proposed based on scattering matrix decomposition, via Pauli matrices. This scheme operates with the Pauli target vectors instead of the scattering matrix. The base elements of the ... -

Transpolarizing trihedral corner reflector characterization using a GB-SAR system
Ferrer, Pere J.; López Martínez, Carlos; Aguasca Solé, Alberto; Pipia, Luca; González Arbesú, José María; Fabregas Canovas, Francisco Javier; Romeu Robert, Jordi (2011-07)
Article
Accés restringit per política de l'editorialThe use of a low-profile, lightweight, and easy-to-fabricate transpolarizing surface placed on one side of a trihedral corner reflector (TCR) as a polarimetric calibrator is presented in this letter. The transpolarizing ... -
