Effects of the Last Quaternary Glacial Forebulge on Vertical Land Movement, Sea‐Level Change, and Lithospheric Stresses

Reviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract A glacial forebulge is a bending‐related upheaval of the lithosphere outside a glaciated area that co‐occurs to the depression of the lithosphere below an ice sheet. The forebulge of the last glaciation attracted attention over more than one century, but quantitative descriptions on the geometry of the forebulge are rare.

A reweighted matrix completion algorithm for sparse inverse synthetic aperture radar imaging

IET Radar, Sonar & Navigation, 2023
Sparse inverse synthetic aperture radar (ISAR) imaging can be generally achieved by compressed sensing (CS) methods because sparse sampling disables the approach of conventional range Doppler. However, the CS‐based methods have to convert the matrix into

Twenty‐Five Years of Probabilistic Fault Displacement Hazard Assessment

Reviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract Fault displacement hazard poses significant risks to critical infrastructure such as buildings, roads, and pipelines. While some structures can tolerate a certain degree of surface displacement, others, such as buildings, are far more vulnerable. Probabilistic Fault Displacement Hazard Assessment (PFDHA) quantifies the probability of exceeding

Multibeam single frequency synthetic aperture radar processor for imaging separate range swaths [PDF]

, 1982
A single-frequency multibeam synthetic aperture radar for large swath imaging is disclosed. Each beam illuminates a separate ""footprint'' (i.e., range and azimuth interval).

Micro-motion Recognition of Spatial Cone Target Based on ISAR Image Sequences

Journal of Aerospace Technology and Management, 2016
The accurate micro-motions recognition of spatial cone target is the foundation of the characteristic parameter acquisition. For this reason, a micro-motion recognition method based on the distinguishing characteristics extracted from the Inverse ...

An Efficient Preprocessing Approach for Airborne Hybrid SAR and ISAR Imaging of Ship Target Based on Kernel Distribution

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The airborne hybrid synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR) imaging for the ship target is very important in the field of ocean surveillance, but it suffers from the problem of high computational complexity.

3D Volumetric Strain Distribution of the Cerro Prieto Geothermal Field Inferred From Inverse Modeling of InSAR and Leveling Data

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Advanced Interferometric Synthetic Aperture Radar (InSAR) data has led to an extensive observation of Earth's surface displacements. Whereas the combined use of high‐resolution InSAR, leveling and GPS data may enable highly detailed three‐dimensional deformation models, publicly available modeling and inversion algorithms either seek a single ...

Modelling of the Seasonal Snow Cover Dynamics for Open and Forested Areas in the Berchtesgaden National Park (Germany) Using the openAMUNDSEN Mountain Snow Cover Model

Hydrological Processes, Volume 39, Issue 7, July 2025.
We capture the snow cover variability in Berchtesgaden National Park (Bavaria, Germany) depending on topography, snow‐canopy processes, and differences between snow‐poor and snow‐rich winters by means of distributed simulations. Our results point out that snow cover duration and snow disappearance day are highly variable in time and space and that snow
