SAR Compact Polarimetry for Change Detection and Characterization
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019 Coherent and incoherent exploitation of complex-valued, synthetic aperture radar imagery separated by temporal and/or spatial baselines can provide significant information for change detection. The majority of the existing techniques, however, deal with the single-channel coherency or correlation for change analysis.

Hybrid Dual-Polarization Synthetic Aperture Radar
Remote Sensing, 2019 Compact polarimetry for a synthetic aperture radar (SAR) system is reviewed. Compact polarimetry (CP) is intended to provide useful polarimetric image classifications while avoiding the disadvantages of space-based quadrature-polarimetric (quad-pol) SARs.

Compact polarimetry assessment for rice and wetland mapping [PDF]
International Journal of Remote Sensing, 2012 Polarimetric RADARSAT-2 data of rice and wetlands are used to simulate compact polarimetry CP mode data from the upcoming RADARSAT Constellation Mission RCM. The simulated CP data are then used to evaluate the information content for rice and wetland mapping using supervised classification, and the results are compared for linear and circular ...

Ship and Oil-Spill Detection Using the Degree of Polarization in Linear and Hybrid/Compact Dual-Pol SAR [PDF]
, 2012 Monitoring and detection of ships and oil spills using synthetic aperture radar (SAR) have received a considerable attention over the past few years, notably due to the wide area coverage and day and night all-weather capabilities of SAR systems.

Pauli Phase Calibration in Compact Polarimetry
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018 In this paper, we consider the problem of true transmitter polarization state estimation for circular compact SAR modes. We employ two methods—the first using point targets such as trihedral reflectors, and the second, a new method, based on the Pauli phase observed over distributed targets like forest canopy.
