Rotational modulation of the linear polarimetric variability of the cool dwarf TVLM 513$-$46546

, 2015
Aims: We aimed to monitor the optical linear polarimetric signal of the magnetized, rapidly rotating M8.5 dwarf TVLM 513$-$46546. Methods: $R$- and $I$-band linear polarimetry images were collected with the ALFOSC instrument of the 2.56-m Nordic ...

Experimental validations of insect orientation extraction based on fully polarimetric measurement

The Journal of Engineering, 2019
The purpose of this study is to demonstrate that the fully polarimetric radar can be effectively used to measure the insect orientation. First, the polarisation scattering matrix (PSM)-based orientation extraction method is reviewed.

PCCN: Polarimetric Contexture Convolutional Network for PolSAR Image Super-Resolution

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Polarimetric synthetic aperture radar (PolSAR) can acquire full-polarization information, which is the solid foundation for target scattering mechanism interpretation and utilization. Meanwhile, PolSAR image resolution is usually lower than the synthetic

LuTan-1: First Demonstration of Hybrid-Polarimetric Synthetic Aperture Radar—Assessing Application Potentials and Performance Constraints

Journal of Remote Sensing
The hybrid-polarimetric (HP) mode is an emerging synthetic aperture radar polarimetric mode that offers a wider swath and improved range ambiguity performance compared to the quadrature-polarimetric (QP) mode, with a slight loss of polarimetric ...
