A Compact Polarimetric CTLR Mode Calibration Method Immune to Faraday Rotation Using Two Dihedral Reflectors

open access: yesRemote Sensing
This paper proposes a compact polarimetric CTLR mode calibration method using only two dihedral reflectors. The method leverages the property that the dihedral scattering matrix is unaffected by double-pass Faraday rotation, effectively eliminating the ...

All-Season Compact-Polarimetry C-band SAR Observations of Sea Ice

open access: yesCanadian Journal of Remote Sensing, 2015
Abstract. Compact-polarimetry (CP) synthetic aperture radar (SAR) observations are presented for major sea ice types in each ice season. CP data for three wide-swath Radarsat Constellation Mission (RCM) modes were simulated and evaluated. Regression models and statistical distances as functions of incidence angles were calculated for 26 CP parameters ...

X-Ray Polarimetry in the Low-statistics Regime Using the Bayesian Approach Reveals Polarization Angle Variations

open access: yesThe Astrophysical Journal
X-ray polarimetry of the accreting compact object has revealed fast time variations in the polarization angle (PA), suggesting that the geometry and/or optical depth of the Comptonization region is changing rapidly.

Spin Tetrad Formalism of Circular Polarization States in Relativistic Jets

open access: yesUniverse
Relativistic jets from active galactic nuclei (AGN) have been a topic of peak interest in the high-energy astrophysics community for their uniquely dynamic nature and incredible radiative power emanating from supermassive black holes and similarly ...
