Pasture Monitoring Using SAR with COSMO-SkyMed, ENVISAT ASAR, and ALOS PALSAR in Otway, Australia

Remote Sensing, 2013
Because of all-weather working ability, sensitivity to biomass and moisture, and high spatial resolution, Synthetic aperture radar (SAR) satellite images can perfectly complement optical images for pasture monitoring.

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.

Design of a millimetre Synthetic Aperture Radar (SAR) onboard UAV's

2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007
This paper describes the design for an experimental short-range (2 Km) high-resolution (30 x 30 cm²) synthetic aperture radar (SAR) sensor in the millimetre wave band to take it onboard unmanned aerial vehicles (UAV). The novelty lies on the establishment of new and very demanding requirements induced by the need of being onboard low cost aerial ...

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 ...

RS‐FloodXDepth: Enhancing Remote Sensing‐Derived Flood Extent and Estimating Flood Depth Using a Hydrologically Guided Region‐Growing Method and High‐Resolution DEMs

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Remote sensing imagery is widely utilized for mapping flood extents. However, sensor limitations and environmental conditions often reduce mapping capability. Factors such as obscuring clouds, terrain shadows, and dense tree canopies frequently lead to significant information gaps and omission errors, particularly in forests and urban areas ...
