A Multiparameter Polarimetric Radar Simulator

Journal of Atmospheric and Oceanic Technology, 2001
Abstract A polarimetric multiparameter radar simulator is described here that is able to reproduce the in-phase and in-quadrature components of the radar echo associated to a population of nonspherical raindrops that is moving under the effect of fall speed, wind, and turbulence.

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 ...

Polarimetric radar images

, 2014
Ce manuscrit concerne une synthèse de mes travaux de recherches menés au sein de l'Onera sur les images polarimétriques radar de télédétection. Un radar polarimétrique permet de mesurer un plus grand nombre de paramètres qu'un radar monocanal en exploitant la nature vectorielle de l'onde électromagnétique.

Polarimetric Radar for Automotive Applications

, 2019
Current automotive radar sensors prove to be a weather robust and low-cost solution, but are suffering from low resolution and are not capable of classifying detected targets. However, for future applications like autonomous driving, such features are becoming ever increasingly important.

Polarimetric clutter modeling: Theory and application [PDF]

The two-layer anisotropic random medium model is used to investigate fully polarimetric scattering properties of earth terrain media. The polarization covariance matrices for the untilted and tilted uniaxial random medium are evaluated using the strong ...

Power Line Polarimetric Imaging by Helicopter Radars: Modeling and Experimental Validation

Mathematics
Onboard millimeter-wave radar is one way to improve helicopter flight safety at low altitudes in difficult meteorological conditions. Low-altitude flight is associated with the risk of collision with low-visibility obstacles such as power lines.
