QUALITY ASSESSMENT OF AN EXTENDED INTERFEROMETRIC RADAR DATA PROCESSING APPROACH [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Radar data acquisition is a reliable technology to provide base data for topographical mapping. Its flexibility and weather independency makes radar data more attractive in comparison with traditional airborne data acquisition.

Validation of a Particle Image Velocimetry Algorithm Through Comparative Field and Laboratory Analysis

River Research and Applications, Volume 42, Issue 8, Page 1654-1672, October 2026.
ABSTRACT Flow velocity measurement is fundamental to hydrological and hydraulic studies, providing essential data for streamflow estimation and river dynamics analysis. Traditional in situ methods like propeller gauges and acoustic Doppler current profilers are accurate but intrusive and labour‐intensive, while non‐intrusive image processing methods ...

Segmentation of Oil Spills on Side-Looking Airborne Radar Imagery with Autoencoders

Sensors, 2018
In this work, we use deep neural autoencoders to segment oil spills from Side-Looking Airborne Radar (SLAR) imagery. Synthetic Aperture Radar (SAR) has been much exploited for ocean surface monitoring, especially for oil pollution detection, but few ...

Downscaling of Tropical Cyclone Surface Wind Fields With a Hybrid Attention Transformer

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract This study employs a Hybrid Attention Transformer‐based super‐resolution model to reconstruct tropical cyclone (TC) surface wind fields. The model downscales coarse‐resolution ERA5 reanalysis data to high‐resolution HWind analyses (1998–2013), increasing the horizontal resolution by a factor of five.

Ground Penetrating Radar Observations of Subsurface Structures From the Makgadikgadi Pans (Botswana): A Terrestrial Analogue of Martian Playa Lakes

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...

Relating Monthly to Yearly Morphological Changes in Embryonic Coastal Dune Systems

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Embryonic coastal dunes are dynamic morphological features shaped by wind, waves, sediment availability, and vegetation. Temporal variability in these drivers controls embryo dune dynamics at short timescales (hours–days), while accreting dune systems often show gradual change over longer timescales (years–decades).
