Prior Aperture Realizations From Far‐Field Stress Approximation for Ensemble‐Based Data Assimilation in Naturally Fractured Reservoirs

Water Resources Research, Volume 61, Issue 9, September 2025.
Abstract Fractures are ubiquitous in reservoirs used for geothermal heat extraction, CO2 storage, and other subsurface applications. Their significant impact on flow and transport requires accurate characterization for performance estimation and risk assessment.

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.

GLRT‐based detection of targets composed of distributed scattering centres

IET Radar, Sonar & Navigation
Attributed scattering problems have been found to be helpful in inverse synthetic aperture radar (ISAR) imaging and target recognition problems. In this model, the scattering centres are divided into two categories: localised and distributed.

Sparse representation-based SAR imaging [PDF]

, 2009
There is increasing interest in using synthetic aperture radar (SAR) images in automated target recognition and decision-making tasks. The success of such tasks depends on how well the reconstructed SAR images exhibit certain features of the underlying ...

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

2-D Coherence Factor for Sidelobe and Ghost Suppressions in Radar Imaging [PDF]

, 1956
The coherence factor (CF) is defined as the ratio of coherent power to incoherent power received by the radar aperture. The incoherent power is computed by the multi-antenna receiver based on only the spatial variable.

Complex-valued interferometric inverse synthetic aperture radar image compression base on compressed sensing

The Journal of Engineering, 2014
Complex-valued interferometric inverse synthetic aperture radar (InISAR) image compression is discussed in this study. The target scene has its continuity and is compressible.
