PUSIF-DUNet: Deep SAR Imaging Network With Joint Optimization on Learnable Probabilistic Undersampling and Unambiguous Reconstruction

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Since the minimum antenna area constraint in the spaceborne single-channel synthetic aperture radar (SAR), it's difficult to achieve high-resolution and wide-swath imaging simultaneously.

Checking Wilderness Through Conservation Genetics: The Case of the European Wildcat in the Central Apennines, Italy

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We developed a species distribution model to assess habitat suitability for the European wildcat across Italy, integrating newly collected occurrence records and mitochondrial DNA data from the Central–Southern Apennines. Forest and grassland cover and elevation emerged as the main predictors of occurrence, with the highest suitability concentrated in ...

High Resolution Field Observations of Shoreward Sediment Transport Within the Wave Bottom Boundary Layer on a Sandy Beach

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract We introduce a data archive containing the first highly resolved profiles of velocity and sediment concentration within the wave bottom boundary layer (WBBL) on a natural sandy beach. Resolution of the thin WBBL was made possible by deployment of a unique “Multi‐Frequency Doppler” (MFDop) bistatic acoustic profiling instrument on an Oregon ...

Mapping the Crustal Thickness of the Andes Using pmP Phases Identified From Adaptive Teleseismic Array Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Crustal thickness (or Moho depth) is a key parameter for many geological and geophysical models. Despite this we have a limited number of measurements, typically from seismic receiver functions, to constrain variations in crustal thickness.

Estimation of Range Ambiguities for Correlation Based Calibration

, 2023
There is an evolutionary trend for Synthetic Aperture Radar (SAR) missions to employ multiple channels in azimuth and elevation. Paired with Digital Beam-Forming (DBF) techniques, it allows to achieve a high resolution and a wide swath. In elevation, a

Imaging the Alpine Collision With Seismic Radial Anisotropy

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Alpine region and the adjacent Northern Apennines (NA) and Northern Dinarides record the complex tectonic evolution associated with the collision between the Eurasian and Adriatic plates. We combine Rayleigh and Love surface waves from ambient noise and earthquake data recorded at over 3,300 seismic stations to construct a high‐resolution ...

Toward a More Physical Representation of Convective Gravity Waves in GFDL’s GCM

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract We implemented in GFDL's global atmospheric model a parameterization for convective gravity waves, which explicitly describes the wave source based on the latent heating rates from the parameterized deep convection. The characteristics of the simulated Quasi‐Biennial Oscillation (QBO) in the equatorial stratosphere depend on the tunable ...

Minimizing Peak Sidelobe Level in MIMO-SAR Waveform Design Using a 1.5-Entmax Sparse Loss

Remote Sensing
The peak sidelobe level (PSL) of an orthogonal waveform set directly governs the range and azimuth ambiguities of synthetic aperture radar (SAR) images and is therefore a key figure of merit for the imaging quality of multiple-input multiple-output SAR ...

Obtaining Local‐Tie Vectors From Short‐Baseline Interferometry Between Legacy S/X and VGOS Telescopes at Ny‐Ålesund

Radio Science, Volume 61, Issue 9, September 2026.
Abstract With the ongoing transition for geodetic Very Long Baseline Interferometry (VLBI) from the use of legacy S/X telescopes to the VLBI Global Observing System (VGOS), it is necessary to connect the new VGOS network to the existing legacy S/X telescopes.
