A Method for Estimating the Polarimetric Scattering Matrix of Moving Target for Simultaneous Fully Polarimetric Radar

Sensors, 2018
To precisely obtain the polarimetric scattering matrix (PSM) of moving target, a measurement model for the simultaneous fully polarimetric radar is formulated. The calibration errors and isolation of the transmitted waveforms are considered.

Synergistic Pyro‐Phototronics and Structural Anisotropy in CsAg2I3/GaN Heterostructures for High‐Performance Polarization‐Sensitive UV Photodetectors

Advanced Science, Volume 13, Issue 31, 4 June 2026.
The development of polarization‐sensitive ultraviolet photodetectors is limited by poor heterojunction quality and low polarization sensitivity. This study integrates synthesized CsAg2I3 single crystals with intrinsic non‐centrosymmetry into van der Waals heterojunction devices, demonstrating pronounced pyro‐phototronic effect.

Bayesian polarization calibration and imaging in very long baseline interferometry

Astronomy & Astrophysics
Context. Extracting polarimetric information from very long baseline interferometry (VLBI) data is demanding but vital to understanding the synchrotron radiation process and the magnetic fields of celestial objects, such as active galactic nuclei (AGNs).

A Non-Parametric Texture Descriptor for Polarimetric SAR Data with Applications to Supervised Classification [PDF]

, 2014
The paper describes a novel representation of polarimetric SAR (PolSAR) data that is inherently non-parametric and therefore particularly suited for characterising data in which the commonly adopted hypothesis of Gaussian backscatter is not ...
