A Joint Moving Target Detection Method in Video SAR Via Low-Rank Sparse Decomposition and Transformer

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Video synthetic aperture radar (SAR) has exhibited considerable potential for detecting and tracking ground moving targets. Numerous classical shadow-based detection methods have been applied in video SAR.

Enhancing Feature Representation of Infrared Foundation Model Using Off‐the‐Shelf Vision Foundation Models

open access: yesElectronics Letters, Volume 62, Issue 1, January/December 2026.
Two pre‐training methods are proposed to leverage off‐the‐shelf vision foundation models to improve the feature representations of an infrared foundation model. Experiments conducted on two downstream tasks each with two distinct datasets show that vision foundation models pre‐trained on natural images effectively benefit infrared model pre‐training ...

Dynamic Multistatic Synthetic Aperture Radar Imaging: Resolving Motion via Differential Semblance and k‐Space Diversity

open access: yesIET 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 ...
