Hybrid polarimetry inverse synthetic aperture radar

IET Radar, Sonar & Navigation
The inverse synthetic aperture radar (ISAR) system exploits the movement of the target to form its high‐resolution image. Further, the multi‐polarisation acquisition in ISAR collects additional information on the target's scattering properties and ...

Exact spectrum of non-linear chirp scaling and its application in geosynchronous synthetic aperture radar imaging

The Journal of Engineering, 2013
Non-linear chirp scaling (NLCS) is a feasible method to deal with time-variant frequency modulation (FM) rate problem in synthetic aperture radar (SAR) imaging.

Detecting peat‐like behaviour areas using European Ground Motion Service data

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
This study presents a scalable approach for detecting peat‐like behaviour areas (PBAs) using open‐access InSAR time series from the European Ground Motion Service. The method integrates unsupervised principal component analysis (PCA) and k‐means clustering to complement optical mapping and reveal peat‐like dynamics, supporting improved peatland ...

Endothelial Integrin‐Linked Kinase (ILK) Deficiency Promotes Endothelial Activation and Cardiovascular Dysfunction via Receptor Interacting Protein Kinase‐1 (RIPK1) Enriched‐Extracellular Vesicle Signalling

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
Endothelial ILK loss drives RIPK1‐enriched EVs that propagate systemic endothelial activation and cardiovascular remodelling. EV cargo remodelling induces early endothelial injury, microvascular dysfunction and chronic cardiac alterations through a RIPK1 dependent pathway.

Vertical and Spatial Geochemical Variations of Nishinoshima Volcaniclastic Deposits, Japan, During Episode 4

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Nishinoshima is a volcanic island in the Ogasawara Arc that has exhibited intermittent activity since 2013, including four major eruptive episodes: 2013–2015 (Episode 1), 2017 (Episode 2), 2018 (Episode 3), and 2019–2020 (Episode 4). Previous studies reported a change in eruption style—from a Strombolian eruption with lava flows (Episode 1 to the early

Spaceborne Radar Technologies for Earth Remote Sensing

, 2007
Synthetic Aperture Radar (SAR) is an indispensable source of information in earth observation since SAR is the only spaceborne sensor that has highresolution, all-weather and day-and-night imaging capability.

The United States Magnetotelluric Array and the National Impedance Map

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

To Which Extent the Surface Water Ocean Topography (SWOT) Mission Is Currently Able to Monitor Water Surface Elevation and Extent on the French Lakes?

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract This study (July 2023–December 2025) assesses the SWOT satellite's ability to measure water surface elevation (WSE) and surface water extent (SWE) over diverse French lakes. WSE estimates from SWOT were compared to in situ gauge data and conventional radar altimetry, while SWE was evaluated using the Global Water Watch (GWW) database.
