During the last two decades, an increasing number of spaceborne Synthetic Aperture Radar (SAR) systems have been equipped with polarimetric capabilities, as for instance, ALOS and ALOS-2, Radarsat-2, TerraSAR-X, Envisat-ASAR, Sentinel-1a/b, etc. Future planned mission will still present this type of diversity where some examples are RCM, SAOCOM and SAOCOM-CS, Cosmo-Skymed 2nd generation or PAZ. In addition, an increasing number of airborne and even ground-based SAR systems are adopting polarimetric capabilities.
As it has been demonstrated extensively in the past, polarimetry makes it possible to have sensitivity to the structural and geometric properties of the targets under observation, allowing a more accurate identification and classification than non-polarimetric systems. Then, polarimetry has made possible new applications, especially in quantitative extraction of new bio and geophysical parameters. It has been also shown that the combination of polarimetry and interferometry makes it possible an unprecedented sensitivity to the vertical structure of semi-transparent media, such as crops or forests.
Consequently, SAR polarimetry has been an active and fruitful field of research in Earth observation. Besides the development of applications, many researchers have also focused their efforts in theoretical aspects or physical modelling to make SAR polarimetry a truly operative remote sensing technique.
The aim of this Special Issue is to present the state of the art in SAR Polarimetry, ranging from theory and physical modeling to final applications, but also to show the current and futures challenges of SAR Polarimetry with the availability of new sources of data. Therefore, this Special Issue puts also the emphasis on studies for the exploitation of data provided by the new polarimetric space borne SAR sensors, which include additional frequency bands, interferometric capability, enlarged spatial coverage, high spatial resolution and/or shorter revisit times.
This Special Issue of the journal Applied Sciences, “Polarimetric SAR Techniques and Applications”, aims to attract novel contributions covering a wide range of aspects related to PolSAR, from theory and techniques to applications. Our topics of interest include, but are not limited to:
• Fundamental theory of SAR polarimetry
• New processing techniques for PolSAR data: calibration, filtering, classification, etc.
• New or improved target decompositions theorems for PolSAR data,
• Operational or future applications of PolSAR data,
• Combination of PolSAR with interferometry, differential interferometry or other sources of diversity,
• Time series exploitation and change detection based on PolSAR data,
• Data fusion among PolSAR sensors or with other type of data.
