    Multilooking is an effective speckle reduction tool for InSAR images. However, it has some limitations. Based on the De-specKS and NL-SAR algorithms, an adaptive multilooking scheme for multi-temporal InSAR data has been ...
  • An adaptive scattering-mechanism-based filtering for multi-temporal pol(In)SAR data 

    Zhao, Feng; Mallorquí Franquet, Jordi Joan (VDE Conference Publications, 2018)
    Conference report

    Pixel selection is a critical procedure in DInSAR processing. In this paper a new temporal phase coherence (TPC) estimation algorithm is proposed for the pixel selection. TPC is calculated based on the estimated interferometric ...
  • A temporal phase coherence estimation algorithm and its application on DInSAR pixel selection 

    Zhao, Feng; Mallorquí Franquet, Jordi Joan (Institute of Electrical and Electronics Engineers (IEEE), 2019-11-01)
    Article
    Open Access
    Pixel selection is a crucial step of all advanced Differential Interferometric Synthetic Aperture Radar (DInSAR) techniques that have a direct impact on the quality of the final DInSAR products. In this paper, a full-resolution ...
  • Coherency Matrix Decomposition-Based Polarimetric Persistent Scatterer Interferometry 

    Zhao, Feng; Mallorquí Franquet, Jordi Joan (Institute of Electrical and Electronics Engineers (IEEE), 2019-10-01)
    Article
    Open Access
    The rationale of polarimetric optimization techniques is to enhance the phase quality of the interferograms by combining adequately the different polarization channels available to produce an improved one. Different ...
  • Landslide monitoring using multi-temporal SAR interferometry with advanced persistent scatterers identification methods and super high-spatial resolution terraSAR-X Images 

    Zhao, Feng; Mallorquí Franquet, Jordi Joan; Iglesias González, Rubén; Gili Ripoll, José Antonio; Corominas Dulcet, Jordi (Multidisciplinary Digital Publishing Institute (MDPI), 2018-06-01)
    Article
    Open Access
    Landslides are one of the most common and dangerous threats in the world that generate considerable damage and economic losses. An efficient landslide monitoring tool is the Differential Synthetic Aperture Radar Interferometry ...
  • SMF-POLOPT: an adaptive multitemporal pol(DIn)SAR filtering and phase optimization algorithm for PSI applications 

    Zhao, Feng; Mallorquí Franquet, Jordi Joan (Institute of Electrical and Electronics Engineers (IEEE), 2019-09-01)
    Article
    Open Access
    Speckle noise and decorrelation can hamper the application and interpretation of PolSAR images. In this paper, a new adaptive multitemporal Pol(DIn)SAR filtering and phase optimization algorithm is proposed to address these ...
