    • Assessing hypertemporal SENTINEL-1 COHERENCE maps for LAND COVER monitoring 

      Vicente Guijalba, F.; Duro, Javier; Notarnicola, Claudia; Jacob, Alexander; Mallorquí Franquet, Jordi Joan; López Martínez, Carlos; Pottier, Eric; López Sánchez, Juan Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper presents the main concepts and the initial analysis of the ESA SEOM project SInCohMap “EXPLOITATION OF SENTINEL-1 INTERFEROMETRIC COHERENCE FOR LAND COVER AND VEGETATION MAPPING”. The project evaluates the ...

    • Basic principles of SAR polarimetry 

      López Martínez, Carlos; Pottier, Eric (Springer, 2021)
      Capítol de llibre
      Accés obert
      This chapter critically summarizes the main theoretical aspects necessary for a correct processing and interpretation of the polarimetric information towards the development of applications of synthetic aperture radar (SAR) ...

    • Coherence estimation in synthetic aperture radar data based on speckle noise modeling 

      López Martínez, Carlos; Pottier, Eric (Optical Society of America, 2007-02-28)
      Article
      Accés obert
      In the past we proposed a multidimensional speckle noise model to which we now include systematic phase variation effects. This extension makes it possible to define what is believed to be a novel coherence model able to ...

    • Influence of speckle filtering of polarimetric SAR data on different classification methods 

      Fang, Cao; Deladalle, Charles-Alban; Nicolas, Jean-Marie; Tupin, Florence; Denis, Loic; Ferro-Famil, Laurent; Pottier, Eric; López Martínez, Carlos (IEEE, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper analyzes the effects of speckle filtering on polarimetric SAR decomposition and classification. We compared the results of the refined Lee, IDAN and Non-Local Polarimetric filters, and discussed their ALOS/PALSAR ...

    • Multidimensional speckle noise model 

      López Martínez, Carlos; Fabregas Canovas, Francisco Javier; Pottier, Eric (Hindawi Publishing Corporation., 2005-12-31)
      Article
      Accés obert

    • On the extension of multidimensional speckle noise model from single-look to multilook SAR imagery 

      López Martínez, Carlos; Pottier, Eric (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-02-28)
      Article
      Accés obert
      Speckle noise represents one of the major problems when synthetic aperture radar (SAR) data are considered. Despite the fact that speckle is caused by the scattering process itself, it must be considered as a noise source ...

    • Polarimetric speckle noise effects in quantitative physical parameters retrieval 

      López Martínez, Carlos; Hajnsek, I.; Lee, J. S.; Pottier, Eric; Fabregas Canovas, Francisco Javier (IEE-INST ELEC ENG, 2006-06-30)
      Article
      Accés obert
      Quantitative estimation of physical parameters of the Earth's surface is currently an active area of research. Multidimensional synthetic aperture radar (SAR) systems appear in this framework as a tool capable of performing ...

    • Sincohmap: land-cover and vegetation mapping using multi-temporal sentinel-1 interferometric coherence 

      Vicente Guijalba, F.; Jacob, Alexander; López-Sánchez Sánchez, Juan Manuel; López Martínez, Carlos; Duro Calvo, Javier; Pottier, Eric; Mallorquí Franquet, Jordi Joan (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      InSAR coherence is a promising parameter for land-cover classification and mapping. The ESA SEOM SInCohMap project is devised to test and analyze multi-temporal InSAR coherence potentialities exploiting dense multitemporal ...

    • Wavelet Transform-Based Interferometric SAR Coherence Estimator 

      López Martínez, Carlos; Fabregas Canovas, Francisco Javier; Pottier, Eric (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-12-31)
      Article
      Accés obert
      A novel method to estimate interferometric coherence in synthetic aperture radar interferometry is proposed. It is demonstrated that this approach is not affected by the terrain topography, contrary to multilook techniques. ...
