Simulation of polarimetric radar variables in rain at S-, C- and X-band wavelengths [PDF]

open access: yesAdvances in Geosciences, 2008
Polarimetric radar variables of rainfall events, like differential reflectivity <i>Z</i><sub>DR</sub>, or specific differential phase <i>K</i><sub>DP</sub>, are better suited for estimating rain rate <i ...

INDREX-II - Tropical Forest Height Estimation with L- and P-Band Polarimetric Interferometric SAR [PDF]

open access: yes, 2006
Tropical forests are complex, heterogeneous, dense, remote and changing forest ecosystems. Low frequency synthetic aperture Radar (SAR) techniques allow monitoring and potentially estimation of key forest parameters such as vertical structure (height ...

On the statistics of differential phases in C-band weather radar [PDF]

open access: yesAdvances in Radio Science, 2007
Differential phases open a new parameter in polarimetric weather radar data analysis. In polarimetric <b>S</b>-matrices measured at the linear polarisation bases (vertical and horizontal) there exist basically three differential phases namely

Flood Inundation Modeling Using the Surface Water Ocean Topography Mission

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract Flood risk mapping requires detailed river bathymetry, yet these data are unavailable for most rivers. We propose a new algorithm to estimate river bathymetry from multitemporal observations of water height by the Surface Water and Ocean Topography (SWOT) mission.

PolSAR Image Modulation Using a Flexible Metasurface with Independently Controllable Polarizations

open access: yesRemote Sensing
Recent advances in time-modulated metasurfaces (TMMs) have introduced approaches for controlling target features in radar imaging. These technologies enable dynamic reconstruction of scattering center locations and intensities by flexibly manipulating ...

Frozen Differential Scattering in Reconfigurable Complex Media

open access: yesLaser &Photonics Reviews, Volume 20, Issue 11, 5 June 2026.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

High-resolution measurements of scattering in wheat canopies-implications for crop parameter retrieval [PDF]

open access: yes, 2006
Polarimetric X- and C-band measurements by the University of Sheffield ground-based synthetic aperture radar(GB-SAR)indoor system provide three-dimensional images of the scattering processes in wheat canopies, at resolutions of around a wavelength (3–6 ...

A Turbulence‐Informed Parameterization of Phase Partitioning in Stratiform Mixed‐Phase Clouds for the LMDZ Model

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract High‐latitude clouds, present over the Arctic Ocean, the Southern Ocean and the Antarctic continent, are very often mixed‐phase clouds (MPCs), that is, composed of both supercooled liquid droplets and ice crystals. Despite being essential for the climate of the poles, they remain a major modeling challenge for climate models. In this study, we
