Synthetic-Aperture Radar Radio-Frequency Interference Suppression Based on Regularized Optimization Feature Decomposition Network

Remote Sensing
Synthetic-aperture radar (SAR) can work in all weather conditions and at all times, and satellite-borne radar has the characteristics of short revisiting period and large imaging width.

Alaska‐Yukon Glacier Depths From a Decade of Airborne Radar Sounding

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract NASA's Operation IceBridge employed airborne radar sounders in Alaska and adjacent northwestern Canada between 2012 and 2021 to measure the thickness of the region's glaciers. Here we present the first comprehensive analysis of these data, analyzing ∼31,700 linear‐km of radar profile data to provide over 5,500 linear‐km of ice thickness and ...

Reconstructing Digital Elevation Models From Single Synthetic Aperture Radar Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Traditional radar‐based methods of generating topography involve complex dual‐antenna or formation‐flying satellite configurations, interferometric processing, and specialized expertise. We present an approach for reconstructing digital elevation models (DEMs) from single Synthetic Aperture Radar (SAR) images using deep learning.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

The Influence of Sea Ice and Ice Mélange on Outlet Glacier Dynamics in the Arctic and Antarctic: Recent Progress and Future Challenges

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.
