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 ...

Futuristic prediction of the lagoon coast shorelines using spaceborne Synthetic Aperture Radar (SAR) imagery

Nova Geodesia
The coast is an extremely dynamic ecosystem that is subject to anthropogenic factors and sea level rise. All of this heightens the worry because it combines the elements that produce storm surges and tropical storms, which raise the possibility of shoreline shift and subsequent coastal erosion. The coastal zone is a prime example of a crucial ecosystem

Geologically Recent Formation of Some Tesserae on Venus by Plains Deformation

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Tessera is a pervasively deformed terrain type on Venus generally interpreted as the oldest preserved material on the surface. Large expanses of this terrain type are typically elevated and have been hypothesized to be felsic, perhaps analogous to Earth's continents and even to date from an era with a more Earth‐like climate earlier in Venus ...

Three-dimensional Imaging Algorithm for Multi-azimuth-angle Multi-baseline Spaceborne Synthetic Aperture Radar

Leida xuebao, 2018
Traditional spaceborne Synthetic Aperture Radar (SAR) can acquire three-dimensional (3D) images by using multi-baseline SAR data, which solves the problem of layover in two-dimensional (2D) SAR image, however, there is still a problem of insufficient ...

Remote Sensing of Sea Surface Wind and Wave from Spaceborne Synthetic Aperture Radar

Leida xuebao, 2020
Spaceborne Synthetic Aperture Radar (SAR) can observe the ocean surface with high spatial resolution and wide swath under all-weather conditions, day and night. Thus, it is a crucial microwave sensor for obtaining information on sea surface wind and wave

Potential tropical cyclone movement and intensification factors imaged by spaceborne SAR

npj Climate and Atmospheric Science
Spaceborne synthetic aperture radar (SAR) is a microwave sensor that captures tropical cyclones (TCs) with high spatial resolution. Based on three idealized TC parametric wind models, we provide a comprehensive perspective on TC studies using SAR ...

Wavelet-Based Compressed Sensing for Polarimetric SAR Tomography [PDF]

, 2013
Tomographic synthetic aperture radar (SAR) imaging has been recently formulated in a wavelet-based compressed sensing (CS) framework. This paper reviews the underlying sparsity-driven algorithms for single-channel as well as polarimetric tomography, and ...
