Compressive Sensing for Ground Based Synthetic Aperture Radar
Remote Sensing, 2018 Compressive sensing (CS) is a recent technique that promises to dramatically speed up the radar acquisition. Previous works have already tested CS for ground-based synthetic aperture radar (GBSAR) performing preliminary simulations or carrying out ...

Journal of Field Robotics, Volume 42, Issue 8, Page 4215-4235, December 2025.ABSTRACT In this study, we tackle the problem of surveilling a large area over the sea without access to the global navigation satellite system (GNSS) while searching for the known target vessel. The system utilizes an unmanned aerial vehicle (UAV) equipped with long‐range radio frequency (LoRa) localization and an RGB camera to detect the target ...

Small Structures, Volume 6, Issue 12, December 2025.This work presents a transparent transmissive metasurface (TTM), designed using a conditional generative adversarial network to achieve broadband electromagnetic illusions. The proposed TTM ensures high optical transparency while precisely manipulating electromagnetic waves, demonstrating effectiveness in practical applications such as camouflage ...

Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...
