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.

Estimation of the Degree of Polarization for Hybrid/Compact and Linear Dual-Pol SAR Intensity Images: Principles and Applications [PDF]
, 2013 Analysis and comparison of linear and hybrid/compact dual-polarization (dual-pol) synthetic aperture radar (SAR) imagery have gained a wholly new importance in the last few years, in particular, with the advent of new spaceborne SARs such as the Japanese

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.

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 ...

Compact Polarimetry Synthetic Aperture Radar Ocean Wind Retrieval: Model Development and Validation
, 2021 We have developed C-band compact polarimetry geophysical model functions for RADARSAT Constellation Mission ocean surface wind speed retrieval. A total of 1594 RADARSAT-2 images acquired in quad-polarization SAR imaging mode were collocated with in situ ...

Model-Based Pseudo-Quad-Pol Reconstruction from Compact Polarimetry and Its Application to Oil-Spill Observation [PDF]
, 2015 Compact polarimetry is an effective imaging mode for wide area observation, especially for the open ocean. In this study, we propose a new method for pseudo-quad-polarization reconstruction from compact polarimetry based on the three-component ...
