Multi-aspect SAR-GMTI and Experimental Research on Gaofen-3 SAR Modes
Leida xuebao, 2020 Multi-aspect SAR is a new SAR mode that has two advantages, i.e., long-term observations and a large synthetic-aperture azimuth angle. Previous studies have reported that these unique advantages enable even single-channel systems to have a relatively ...

Remote Sensing During the 2025 Los Angeles Wildfires
AGU Advances, Volume 7, Issue 5, August 2026.Abstract The January 2025 Los Angeles County wildfires burned more than 50,000 acres, destroyed more than 16,000 structures, and caused 31 deaths. This Commentary examines how NASA's Disasters Program coordinated with response organizations to deliver 22 satellite and airborne products during the fires, even as the Eaton Fire forced the Jet Propulsion ...

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Snow on Antarctic sea ice modulates albedo, thermodynamic growth, and snow–ice formation, yet remains a leading uncertainty in altimetry‐derived sea‐ice thickness. Here we use the post‐2022 CRYO2ICE configuration to derive along‐track winter snow thickness from ICESat‐2 laser and CryoSat‐2 Ku‐band radar freeboards over the Weddell and Ross ...

High Voltage, Volume 11, Issue 4, Page 1090-1101, August 2026.ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

First 3-D reconstructions of target hidden beneath foliage by means of polarimetric SAR tomography [PDF]
, 2012 SAR tomography (SARTom) is an imaging technique that allows multiple phase center separation in the vertical direction, leading to a 3-dimensional (3D) reconstruction of the imaged scene. Retrieval of volume structure information (e.g.

Space-borne polarimetric SAR sensors or the golden age of radar polarimetry
EPJ Web of Conferences, 2010 SAR Polarimetry represents an active area of research in Active Earth Remote Sensing. This interest is clearly supported by the fact that nowadays there exists, or there will exist in a very next future, a non negligible quantity of launched ...
