Sea Ice Monitoring by Synthetic Aperture Radar [PDF]
Oceanography, 2013 Satellite-borne synthetic aperture radar (SAR) data are highly valuable not only for observing the open ocean but also for monitoring seasonally or permanently ice-covered ocean regions in the Arctic, Antarctic, and other areas such as the Baltic Sea ...

High Voltage, EarlyView.ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Journal of Imaging, 2016 The dynamics of surface and sub-surface water events can lead to slope instability, resulting in anomalies such as slough slides on earthen levees. Early detection of these anomalies by a remote sensing approach could save time versus direct assessment ...

Does AI Affect the Democratic Conduct of War? Analyzing US and Israeli Military AI Deployment
Global Policy, EarlyView.ABSTRACT This study examines how the use of decision‐support military Artificial Intelligence (AI) systems can affect the democratic conduct of warfare. AI can challenge the democratic conduct of warfare by introducing systemic risks such as reduced oversight, opacity, and automation bias.

Terra Nova, EarlyView.ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

Compressive Sensing for Ground Based Synthetic Aperture Radar
Remote Sensing, 2018 Compressive sensing (CS) is a recent technique that promises to dramatically speed up the radar acquisition. Previous works have already tested CS for ground-based synthetic aperture radar (GBSAR) performing preliminary simulations or carrying out ...

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.Abstract Tropical forests in sub‐Saharan Africa (SSA) harbor around one‐third of the world's species but are becoming more fragmented due to the expansion of human settlements and small‐scale agricultural (SCA) areas. This study systematically reviewed the approaches and methods used to analyze forest fragmentation and its impact on biodiversity in SSA,
