Back projection algorithm-based GEO SAR real-time quick Look imaging system

The Journal of Engineering, 2019
Geosynchronous earth orbit synthetic aperture radar (GEO SAR) has the advantages of short revisit period and wide observation range. However, compared with low earth orbit SAR (LEO SAR), GEO SAR has the distinct characteristics of long synthetic aperture

Adaptive Prototype‐Based Few‐Shot Segmentation for Debris Flow Early Warning

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
From single‐parameter monitoring to a cross‐modal few‐shot visual paradigm for debris flow early warning. Conventional rainfall‐gauge and mud‐level monitoring is data‐sparse, delayed in response, and spatially limited. The proposed framework instead fuses a support set, a query image, and a textual target category through ResNet‐50 and CLIP encoders ...

The Staggered SAR concept: Imaging a wide continuous swath with high resolution [PDF]

, 2013
Staggered SAR is an innovative synthetic aperture radar (SAR) concept, based on the continuous variation of the pulse repetition interval (PRI). This concept allows high-resolution imaging of a wide continuous swath without the need for a long antenna ...

Do Shallow Slip Deficits Reflect Fault Structural Maturity or Modeling Choices? A Comparative Analysis of Tibetan Strike‐Slip Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract InSAR‐constrained finite fault slip models are often used to characterize fault geometries and slip distributions of large continental earthquakes. A common feature of these models is a decrease in slip near the surface, commonly expressed as a percentage shallow slip deficit (SSD).
