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.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Conventional airborne radar sounding techniques are well suited to the detection and characterization of flat-lying, specular subglacial water bodies. However, topographically positive, diffusively scattering Röthlisberger (R-) channels are more ...

CROP SPECIES RECOGNITION AND DISCRIMINATION PADDY-RICE-GROWINGFIELDS FROM REAPED-FIELDS BY THE RADAR VEGETATION INDEX (RVI) OF ALOS-2/PALSAR2 [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 The Japanese ALOS-2 satellite was launched on May 24th, 2014. It has the L-band SAR, PALSAR-2. Kim,Y. and van Zyl, J.J. proposed a kind of Radar Vegetation Index (RVI) as RVI = 8 * σ0hv / (σ0hh + σ0vv + 2* σ0hv) by L-band full-polarimetric radar data ...

On the Gersgorin Theorem Applied To Radar Polarimetry [PDF]
PIERS Online, 2007 This contribution is concerned with the mathematical formulation and theoretical background of the Ger‚sgorin theory in the context of Radar Polarimetry. Named after its founder Semian A. Ger‚sgorin the Ger‚sgorin theorem basically states that there are certain regions in the complex plane that can be derived from any n £ n complex matrix by rather ...
