Color Enhancement for Four-Component Decomposed Polarimetric SAR Image Based on a CIE-Lab Encoding

Remote Sensing, 2018
Color enhancement of decomposed fully polarimetric synthetic aperture radar (PolSAR) image is vital for visual understanding and interpretation of the polarimetric information about the target.

Dual Circular Polarized Drone-Borne SAR for Polarimetric Target Classification: System Development and Experimental Validation

Sensors
Post-disaster scenarios such as tsunamis require rapid terrain assessment that cannot wait for the next satellite synthetic aperture radar (SAR) revisit, yet a readily deployable system remains lacking. We present an off-the-shelf K-band drone-borne dual

Concealed Object Discrimination in Forested Areas Using PolTomoSAR with Various Baseline Configurations [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Detecting objects hidden beneath a forest cover with Synthetic Aperture Radar (SAR) is challenging due to strong vegetation scattering, canopy attenuation, and ground returns.

Sub-Canopy Topography Estimation: Experiments With Multibaseline SAR Data at L-Band [PDF]

, 2012
Synthetic aperture radar (SAR) systems in L-band and P-band are characterized by deep penetration capabilities into volumes, enabling new opportunities for the radar remote sensing of forests. In the last years, the interest has been continuously growing

Speckle effect on polarimetric target scattering decomposition of SAR imagery

Canadian Journal of Remote Sensing, 2007
Target scattering decompositions have become the standard tools for scattering classification and for target geophysical parameter extraction from polarimetric synthetic aperture radar (SAR) data. Incoherent decompositions are based on the characteristic decomposition of the target coherency matrix and the use of its eigenvalues and eigenvector ...

Polarimetric characterisation of two layered frozen lakes [PDF]

, 2011
In terms of radar remote sensing, one of the challenges of future planetary SAR missions will be the estimation of surface, subsurface and upper layer geometric and dielectric characteristics that translate to the localization of subsurface ice and water

Polarimetric Scattering Model for Methane Bubbles Trapped in the Ice of Sub-Artic Lakes [PDF]

, 2012
In this work we propose a model for the polarimetric backscattering of shallow sub-arctic lakes, which are frozen usually up to two meters depth during winter.

Refined ship interpretation in compact polarimetric SAR via formalism and joint feature space construction

Geo-spatial Information Science
The two-channel cost of Compact Polarimetric (CP) Synthetic Aperture Radar (SAR) with close performance compared to four-channel Full Polarimetric (FP) SAR, has great potential for observing and interpreting ship targets.

Three-Component Decomposition Based on Stokes Vector for Compact Polarimetric SAR

, 2015
In this paper, a three-component decomposition algorithm is proposed for processing compact polarimetric SAR images. By using the correspondence between the covariance matrix and the Stokes vector, three-component scattering models for CTLR and DCP modes
