Wavelet-Based Compressed Sensing for Polarimetric SAR Tomography [PDF]
Tomographic synthetic aperture radar (SAR) imaging has been recently formulated in a wavelet-based compressed sensing (CS) framework. This paper reviews the underlying sparsity-driven algorithms for single-channel as well as polarimetric tomography, and ...

Polarimetric Calibration of Weather Radar using the Sun [PDF]
The sun is used for weather radar calibration for a long time. It is used to monitor receiver stability and antenna alignment. It will be shown, that the unpolarized signals from the sun can be used for verification of the polarimetric properties of a

Calibration and field experiment of a C-band polarimetric scatterometer
Presents the evaluation results of a full polarimetric C-band scatterometer system that has been designed and constructed at the Multimedia University, Malaysia. The system was tested at a football field. A metal sphere was used as the calibration target.

POLARIMETRIC CALIBRATION OF PALSAR
For spaceborne polarimetric synthetic aperture radar (SAR), it is important to ensure the removal of both polarimetric system distortion and the effect of Faraday rotation. This paper proposes a new calibration method to derive the system distortion using polarization orientation (PO) induced in built-up areas and applies to Phased-Array-Type L-Band ...

Polarimetric calibration of large mirrors
Aims: To propose a method for the polarimetric calibration of large astronomical mirrors that does not require use of special optical devices nor knowledge of the exact polarization properties of the calibration target. Methods: We study the symmetries of the Mueller matrix of mirrors to exploit them for polarimetric calibration under the assumptions ...

Polarimetric characterisation of two layered frozen lakes [PDF]
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
