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.

On the use of compact polarimetry SAR for ship detection

ISPRS Journal of Photogrammetry and Remote Sensing, 2013
Abstract Quad-pol data are generally acknowledged as providing the highest performance in ship detection applications using SAR data. Yet quad-pol data have half the swath width of single and dual-pol data and are thus less useful for maritime surveillance, where wide area coverage is crucial.

Estimation of the degree of polarization in compact polarimetry

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
The degree of polarization (DoP) has long been recognized as one of the most important parameters characterizing partially polarized electromagnetic waves. This parameter can be effectively used to describe the information content of polarimetric images collected by synthetic aperture radar (SAR) systems. Estimation of DoP is standardly performed using

Compact Polarimetry SAR and Compact Polarimetric SAR Interferometry

2021
Polarimetric SAR can obtain more abundant target information compared to ordinary single-polarized synthetic aperture radar. However, the addition of polarimetric ability increases the complexity of SAR system greatly, which imposes demanding requirements for antenna technology, data download rate, and power consumption.
