3D Visualization of Radar Backscattering Diagrams Based on OpenGL [PDF]

EURASIP Journal on Advances in Signal Processing, 2004
Summary: A digital method of calculating the radar backscattering diagrams is presented. The method uses a digital model of an arbitrary scattering object in the 3D graphics package `OpenGL' and calculates the backscattered signal in the physical optics approximation.

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 ...

Unusual SuperDARN Backscatter During the 11 May 2024 Geomagnetic Storm

Space Weather
A geomagnetic storm, one of the largest in this solar cycle, was launched on 10 May 2024, producing spectacular auroral displays that could be observed across the continental United States (US) at middle and low latitudes.

Deterministic chaos at the ocean surface: applications and interpretations [PDF]

Nonlinear Processes in Geophysics, 1998
Ocean surface, grazing-angle radar backscatter data from two separate experiments, one of which provided coincident time series of measured surface winds, were found to exhibit signatures of deterministic chaos.

Sensitivity of L-Band SAR Backscatter to Aboveground Biomass of Global Forests

Remote Sensing, 2016
Synthetic Aperture Radar (SAR) backscatter measurements are sensitive to forest aboveground biomass (AGB), and the observations from space can be used for mapping AGB globally.

Performance Evaluation of Automated Flood Inundation Mapping Techniques Using Multi‐Temporal Sentinel‐1 SAR Data

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT In recent times, the development of algorithms to delineate water surface maps has significantly boosted flood monitoring and mitigation efforts by utilizing dual polarization, multi‐temporal Sentinel‐1 synthetic aperture radar (SAR) data. The Sentinel‐1 mission, with its global land monitoring capability, has been widely employed for SAR ...

Feasibility Mapping of L‐Band InSAR for SWE Retrievals Across the Western United States

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Mountain snowpacks provide vital water resources for communities in the western U.S. (WUS), but high spatial variability challenges accurate measurement of snow water equivalent (SWE) from remote sensing platforms. Studies using repeat airborne L‐band (∼25 cm wavelength) Interferometric Synthetic Aperture Radar (InSAR) have demonstrated ...
