GNSS-based bistatic SAR: a signal processing view [PDF]
, 2013 This article presents signal processing algorithms used as a new remote sensing tool, that is passive bistatic SAR with navigation satellites (e.g. GPS, GLONASS or Galileo) as transmitters of opportunity.

Monitoring Flood Inundation Dynamics From Space
Reviews of Geophysics, Volume 64, Issue 1, March 2026.Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.

A High-Order Imaging Algorithm for High-Resolution Space-Borne SAR Based on a Modified Equivalent Squint Range Model [PDF]
, 2015 Two challenges have been faced in signal processing of ultrahigh-resolution spaceborne synthetic aperture radar (SAR). The first challenge is constructing a precise range model, and the second one is to develop an efficient imaging algorithm since ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Moving targets often appear defocused and displaced in SAR imagery, complicating detection and recognition—especially when displaced into cluttered regions, where signal‐to‐background ratio is reduced. This work presents a multistatic SAR framework that extracts moving target signatures and reconstructs focused images, providing new insights into the ...

Large‐Scale Topographic Changes at Erupting Volcanoes Measured by the TanDEM‐X Digital Change Map
Earth and Space Science, Volume 12, Issue 11, November 2025.Abstract Volcanic eruptions cause large‐scale topographic changes, through the emplacement of lava flows and lava domes, the formation of craters and calderas, and thick ash and pyroclastic deposits. Here we analyze the TanDEM‐X Digital Change Map (DCM), which compares the DEM produced during 2010–2015 with satellite acquisitions collected in 2016–2022.
