Analysis of Crosstalk Impact on the Cloude-decomposition-based Scattering Characteristic

Leida xuebao, 2017
Crosstalk is not only one of the main error sources in the polarimetric SAR system, but is also an indicator for evaluating calibration performance. In this paper, to determine the impact of crosstalk on land cover classification, we first retrieve the ...

Evaluation of Calibration Using Corner Reflector with Ground-Based Interferometric Radar [PDF]

Geo Data
The accuracy of microwave remote sensing relies on the calibration of the radar measurement. It is important to estimate the radar cross-section (RCS) using a passive corner reflector (CR) or active transponder to evaluate the quality of imaging radar ...

Polarimetric calibration of large mirrors

, 2015
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 ...

Polarmetric Consistency Assessment and Calibration Method for Quad-Polarized ScanSAR Based on Cross-Beam Data

Remote Sensing
The range-dependence on polarization distortion of spaceborne polarimetric synthetic aperture radar (SAR) affects the accuracy of wide-swath polarization applications, such as environmental monitoring, sea ice classification and ocean wave inversion ...
