Adaptive polarimetric image representation for contrast optimization of a polarized beacon through fog [PDF]
, 2015 We present a contrast-maximizing optimal linear representation of polarimetric images obtained from a snapshot polarimetric camera for enhanced vision of a polarized light source in obscured weather conditions (fog, haze, cloud) over long distances ...

Polarimetric variations of binary stars. II. Numerical simulations for circular and eccentric binaries in Mie scattering envelopes [PDF]
, 2001 We present numerical simulations of the periodic polarimetric variations produced by a binary star placed at the center of an empty spherical cavity inside a circumbinary ellipsoidal and optically thin envelope made of dust grains.

Comparison of the estimation of the degree of polarization from four or two intensity images degraded by speckle noise [PDF]
, 2006 Active polarimetric imagery is a powerful tool for accessing the information present in a scene. Indeed, the polarimetric images obtained can reveal polarizing properties of the objects that are not avalaible using conventional imaging systems.

On the use of the l(2)-norm for texture analysis of polarimetric SAR data [PDF]
, 2016 In this paper, the use of the l2-norm, or Span, of the scattering vectors is suggested for texture analysis of polarimetric synthetic aperture radar (SAR) data, with the benefits that we need neither an analysis of the polarimetric channels separately ...

Polarimetric radiometer configurations [PDF]
IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998 Ocean wind speed and direction can be assessed with a polarimetric radiometer system measuring the full set of Stokes parameters. The first and second Stokes parameters are the sum and difference of the usual vertical and horizontal brightness temperatures.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Manual selection of the distribution target and determination of its spatial location is not only time consuming but also has a serious impact on the polarimetric channel imbalances assessment if the area is incorrect.

, 2006 The use of polarimetric techniques is nowadays widespread among solar and stellar astronomers. However, notwithstanding the recommandations that have often been made about the publication of polarimetric results in the astronomical literature, we are still far from having a standard protocol on which to conform.

Journal of Telecommunications and Information Technology, 2001 The aim of this work is to develop a coherent polarimetric model and to find a geometrical description of a monochromatic wave. The spinor form of the electrical field, its links to the coherency matrix and the Poincare` sphere are introduced with the ...

IEEE Access, 2020 Polarimetry is typically restricted to far-field characterization of a target using beam-like waves, which results in a 2 x 2 scattering matrix representation under two orthogonal in-plane polarization bases.

POLARIMETRIC MINISAR MAPPING SYSTEM [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Polarimetric MiniSAR is a ku-band fully polarimetric SAR mapping system that is being developed at CASM (Chinese Academy of Surveying and Mapping). The system consists of a ku-band fully polarimetric miniSAR data acquisition system and a set of miniSAR ...
