Spaceborne Radar Technologies for Earth Remote Sensing [PDF]

, 2007
Synthetic Aperture Radar (SAR) is an indispensable source of information in earth observation since SAR is the only spaceborne sensor that has highresolution, all-weather and day-and-night imaging capability.

Smart Multi-Aperture Radar Techniques for Spaceborne Remote Sensing [PDF]

, 2008
Data compression is crucial for modern synthetic aperture radar systems where high resolution or large coverage may result in huge amounts of raw data.

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.

Multichannel False-target Discrimination in SAR Images Based on Sub-aperture and Full-aperture Feature Learning

Leida xuebao, 2021
False targets caused by multichannel Synthetic Aperture Radar (SAR) are similar to a defocused ship in both shape and texture, making it difficult to discriminate in the full-aperture SAR image.

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

Geophysical 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.

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Calibration Issue in SMART Synthetic Aperture Radar Based on Scan-On-Receive [PDF]

, 2009
A new spaceborne Synthetic Aperture Radar (SAR) system based on SCan-On-REceive (SCORE) algorithm has been recently proposed in order to overcome the trade-off between spatial resolution and swath wide of current SAR systems. The compound architecture of

Micro-Motion Estimation of Maritime Targets Using Pixel Tracking in Cosmo-Skymed Synthetic Aperture Radar Data—An Operative Assessment

Remote Sensing, 2019
In this paper, we propose a novel strategy to estimate the micro-motion (m-m) of ships from synthetic aperture radar (SAR) images. To this end, observe that the problem of motion and m-m detection of targets is usually solved using synthetic aperture ...
