Potential of mm‐Wave Doppler‐Polarimetric Profiler Observations for Quality Assessment of Hydrometeor Classification Schemes

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 11, 16 June 2025.
Abstract Dual‐polarization weather radars have improved the accuracy of precipitation estimates. However, challenges persist in evaluating hydrometeor classification (HMC) algorithms, thereby impacting the accuracy of precipitation estimates.

Polarisation Synthesis Applied to 3D Polarimetric Imaging for Enhanced Buried Object Detection and Identification

open access: yesRemote Sensing
Detecting sub-surface objects poses significant challenges, partly due to attenuation of the ground medium and cluttered environments. The acquisition polarisation and antenna orientation can also yield significant variation of detection performance ...

Ocean Wind Retrieval Models for RADARSAT Constellation Mission Compact Polarimetry SAR

open access: yesRemote Sensing, 2018
We propose two new ocean wind retrieval models for right circular-vertical (RV) and right circular-horizontal (RH) polarizations respectively from the compact-polarimetry (CP) mode of the RADARSAT Constellation Mission (RCM), which is scheduled to be ...

Polarimetry of light scattered by surface roughness and textured films and periodic structures in nanotechnologies: a new challenge in instrumentation and modeling

open access: yesEPJ Web of Conferences, 2010
Exhaustive studies in the literature detail the Mueller matrices properties through decomposition, optical entropy and depolarization formalism. It has been applied for many years in rather different fields. In radar polarimetry, mathematical basis of
