  • 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
    Open Access
    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)
    Conference report

    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
    Open Access
  • 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
    Open Access
    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
    Open Access
    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 ...
  • 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
    Open Access
    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. ...
