A Novel Spaceborne Sliding Spotlight Range Sweep Synthetic Aperture Radar: System and Imaging

open access: yesRemote Sensing, 2017
In this paper, a new Spaceborne Sliding Spotlight Range Sweep Synthetic Aperture Radar (SSS-RSSAR) is proposed to generate a high-resolution image of a Region of Interest (ROI) tilted with respect to the satellite track.

Global Improvement of Tropical Cyclone Representation Enhances Hindcasts of Extreme Sea Levels Over 68 Years

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The underrepresentation of tropical cyclones (TCs) in state‐of‐the‐art atmospheric reanalyses such as ERA5 is well known, yet their impact on global hindcasts of extreme sea levels remains largely unaddressed. We show that weak TC signals in ERA5 cause severe underestimation, and in some cases near omission, of TC‐induced storm surges.

Temporal stability of soil moisture and radar backscatter observed by the advanced Synthetic Aperture Radar (ASAR) [PDF]

open access: yes, 2008
The high spatio-temporal variability of soil moisture is the result of atmospheric forcing and redistribution processes related to terrain, soil, and vegetation characteristics.

Phaseless Radar Coincidence Imaging with a MIMO SAR Platform

open access: yesRemote Sensing, 2019
The correlation-based synthetic aperture radar imaging technique, termed radar coincidence imaging, is extended to a fully multistatic multiple-input multiple-output (MIMO) synthetic aperture radar (SAR) configuration.

Discrimination of Truffles and Truffle Oils by a Metal–Organic‐Framework‐Based Electronic Nose

open access: yesAdvanced Sensor Research, Volume 5, Issue 9, September 2026.
A portable electronic nose based on MOF‐coated QCM sensors enables rapid authentication of truffles and truffle‐derived oils. Characteristic response patterns distinguish fresh truffle species, homemade and commercial oils, and samples adulterated with dimethyl sulfide.

The Radiometric Measurement Quantity for SAR Images [PDF]

open access: yes, 2013
A Synthetic Aperture Radar (SAR) system measures among other quantities the terrain radar reflectivity. After image calibration, the pixel intensities are commonly expressed in terms of radar cross sections (for point targets) or as backscatter ...

Hybrid polarimetry inverse synthetic aperture radar

open access: yesIET Radar, Sonar & Navigation
The inverse synthetic aperture radar (ISAR) system exploits the movement of the target to form its high‐resolution image. Further, the multi‐polarisation acquisition in ISAR collects additional information on the target's scattering properties and ...
