Frozen Differential Scattering in Reconfigurable Complex Media

Laser &Photonics Reviews, EarlyView.
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 ...

Polarimetric Synthetic Aperture Radar Speckle Filter Based on Joint Similarity Measurement Criterion

Remote Sensing, 2023
Polarimetric Synthetic Aperture Radar (PolSAR) data is inherently characterized by speckle noise, which significantly deteriorates certain aspects of the quality of the PolSAR data processing, including the polarimetric decomposition and target ...

An icon-based synoptic visualization of fully polarimetric radar data [PDF]

, 2012
The visualization of fully polarimetric radar data is hindered by traditional remote sensing methodologies for displaying data due to the large number of parameters per pixel in such data, and the non-scalar nature of variables such as phase difference ...

Fast Retrieval of Cloud Optical Depth From Polarimetry and Multi‐Spectral Imagery That Accounts for Cloud Heterogeneity Using 3D Radiative Transfer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract We present a method for retrieving cloud optical depth that applies 3D radiative transfer to utilize the combination of polarimetry and multi‐spectral imagery that is newly available from satellite missions such as the Plankton, Aerosol, Cloud, Ocean, Ecosystem (PACE) Mission. Due to the approximate spectral invariance of scattering by clouds,

On the Use of Neumann Decomposition for Crop Classification Using Multi-Temporal RADARSAT-2 Polarimetric SAR Data

Remote Sensing, 2019
In previous studies, parameters derived from polarimetric target decompositions have proven as very effective features for crop classification with single/multi-temporal polarimetric synthetic aperture radar (PolSAR) data.
