Scheme of dynamic polarimetric calibration

open access: yesElectronics Letters, 2012
Proposed is a new scheme of frequency-domain dynamic polarimetric calibration by designing a polarimetric active radar calibrator (PARC) with two rotatable antennas. The proposed scheme can eliminate clutter and the error due to a set of measurements in the traditional static calibration scheme.

Calibration of a polarimetric imaging SAR [PDF]

open access: yes, 1991
Calibration of polarimetric imaging Synthetic Aperture Radars (SAR's) using point calibration targets is discussed. The four-port network calibration technique is used to describe the radar error model.

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

open access: yes, 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.

Investigations on the Polarimetric Behavior of a Target Near the Soil [PDF]

open access: yes, 2006
The polarimetric behavior of the diffracted field from an object located close to the ground is investigated for a varying incidence angle. Here, the field is described by the geometrical theory of diffraction in accordance to its asymptotic formulas. As

Polarimetric PALSAR System Model Assessment and Calibration

open access: yesIGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
Polarimetric PALSAR system parameters are assessed using data sets collected over various calibration sites. The data collected over the Amazonian forest permits validating the zero Faraday rotation hypotheses near the equator. The analysis of the Amazonian forest data and the response of the corner reflectors deployed during the PALSAR acquisitions ...

Polarimetric Calibration Monitoring by Permanent Scatterers

open access: yes, 2010
The PS calibration combines external devices, like corner reflectors, transponders and the stable targets to provide continuous monitoring of the radiometric quality of a SAR instrument.

Foliage penetration effect on polarimetric SAR interferometry observation of forest [PDF]

open access: yes, 2008
The capability of electromagnetic waves to penetrate trough foliage (FOLPEN), combined with the potentialities of the polarimetric SAR interferometry (POL-InSAR) are demonstrated to be valid instruments for the investigation of forest characteristics and
