Doppler polarimetric ground clutter identification and suppression for atmospheric radars based on co-polar correlation

Journal of Telecommunications and Information Technology, 2001
A new clutter suppression technique that uses both Doppler and polarimetric information is presented. Polarimetric properties of the target and clutter are calculated per Doppler frequency cell and based on this information clutter suppression is ...

Optimum graph cuts for pruning binary partition trees of polarimetric SAR images [PDF]

, 2016
This paper investigates several optimum graph-cut techniques for pruning binary partition trees (BPTs) and their usefulness for the low-level processing of polarimetric synthetic aperture radar (PolSAR) images.

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,

Describing the Global Gravity Field of Mars With Lithospheric Flexure and Deep Mantle Flow

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The volcanic complex Tharsis Region on Mars is known for its numerous volcanoes on top of the crust, elevated topography (doming), and a long‐wavelength gravity anomaly correlated with the region. Flexural modeling of the lithosphere has commonly been used to understand the relationship between observed topography, crustal structure, and ...

Polarimetric Adaptive Coherent Detection in Lognorm-Texture-Distributed Sea Clutter

Remote Sensing
This paper addresses polarimetric adaptive coherent detection of radar targets embedded in sea clutter. Initially, radar clutter data across multiple polarimetric channels is modeled using a compound Gaussian framework featuring an unspecified speckle ...

Modifying the Yamaguchi Four-Component Decomposition Scattering Powers Using a Stochastic Distance

, 2015
Model-based decompositions have gained considerable attention after the initial work of Freeman and Durden. This decomposition which assumes the target to be reflection symmetric was later relaxed in the Yamaguchi et al.

Advances in mapping ice-free surfaces within the Northern Antarctic peninsula region using polarimetric RADARSAT-2 data [PDF]

, 2018
Ice-free areas within the Northern Antarctic Peninsula region are of interest for studying changes occurring to surface covers, including those related to glacial coverage, raised beach deposits and periglacial processes and permafrost. The objective

Aerosol‐Cloud Interactions: Overcoming a Barrier to Projecting Near‐Term Climate Evolution and Risk

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Aerosol‐cloud interactions (ACI) are a major source of uncertainty in climate science, critically affecting our ability to project near‐term climate evolution and assess societal risks. These interactions influence effective radiative forcing, cloud dynamics, and precipitation patterns, yet remain insufficiently constrained due to limitations ...
