Calibration Of Polarimetric Radar Systems

12th Canadian Symposium on Remote Sensing Geoscience and Remote Sensing Symposium,, 2005
A practical technique is proposed for calibrating single-antenna polarimetric radar systems using a metal sphere plus any second target with a strong cross-polarized radar cross section. It is shown that all magnitudes and phases (relative to one of the like-polarized linear polarization configurations) of the radar transfer function can be calibrated ...

A New Approach for Polarimetric Calibration

2006 International Conference on Microwaves, Radar & Wireless Communications, 2006
This paper presents a new calibration approach for polarimetric SAR using distributed targets with known scattering matrixes. A genetic algorithm based on complex-valued encoding is used to solve the polarimetric calibration problem, which has multiple variables and over-determined non-linear equations.

Transpolarizing surfaces for polarimetric SAR systems calibration

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
A novel transpolarizing or crosspolarizing surface has been proposed to be applied in polarimetric SAR calibrating systems, like trihedrals, since they can not provide initially a crosspolar response. So the trans-surface has been designed and measured in an anechoic chamber, providing good results for normal incidence.

A new polarimetric active radar calibrator and calibration technique

SPIE Proceedings, 2015
Polarimetric active radar calibrator (PARC) is one of the most important calibrators with high radar cross section (RCS) for polarimetry measurement. In this paper, a new double-antenna polarimetric active radar calibrator (DPARC) is proposed, which consists of two rotatable antennas with wideband electromagnetic polarization filters (EMPF) to achieve ...

The Effect of Calibration Error on Polarimetric Reconstruction in Microgrid Polarimetric Imagery

Frontiers in Optics 2010/Laser Science XXVI, 2010
We explore the effect of expected deviations from ideal components of microgrid imaging polarimeters using simulation and perform a calibration on an implementation of these errors from data taken by a specific instrument.

Developing calibration technology for full-polarimetric GPR

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Polarimetric GPR requires accurate calibration of channel imbalance and crosstalk not only in the amplitude term but also in the phase term. Currently, there have some calibration techniques. Though these techniques are very easy to perform, they provide less accurate calibration results for the crosstalk.

Calibration of polarimetric PHARUS data

1998
This paper presents a procedure for the calibration of polarimetric PHARUS data, based on the JPL POLCALprocedure, including some first results. Because the phase differences between the various polarizationchannels of PHARUS turned out to be range dependent, the procedure had to be adapted by calibrating the phasebefore conversion to Stokes matrix ...
