Digital Beamforming on Receive: Techniques and Optimization Strategies for High-Resolution Wide-Swath SAR Imaging [PDF]

open access: yes, 2009
Synthetic Aperture Radar (SAR) is a well-proven imaging technique for remote sensing of the earth. However, conventional SAR systems are not capable to fulfill the increasing demands for im-proved spatial resolution and wider swath coverage.

Revealing Dust Source Changes in East Asia From Past to Future: An Interpretable Deep Learning Approach

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute

Spaceborne Radar Technologies for Earth Remote Sensing [PDF]

open access: yes, 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.

BridgeSAR: Measuring Bridge‐Water Clearance From Space Using SAR Multipath Signatures

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Bridge‐water clearance controls safe vessel passage and reflects local water‐level changes, but direct measurements are unavailable at many bridges. We present BridgeSAR, a geometry‐guided method that estimates clearance from multipath scattering stripes in synthetic aperture radar (SAR) amplitude images.
