Soil Moisture Retrieval Using Multistatic L-Band SAR and Effective Roughness Modeling

Remote Sensing, 2022
The interest in bistatic SAR systems for soil moisture monitoring has grown over recent years, since theoretical studies suggest that the impact of surface roughness on the retrieval of soil moisture decreases when multistatic, i.e., simultaneous mono ...

Wood Carbon Sponge/SiO2 Aerogel Composites with Anisotropic Broadband Microwave Absorption, Elastic Resilience, and Thermal Insulation

Advanced Science, EarlyView.
Anisotropic wood carbon sponge/SiO2 aerogel composites are constructed, revealing a robust direction‐dependent permittivity ordering (tangential > radial > axial). The radial direction delivers an ultra‐broadband effective absorption bandwidth of 11.6 GHz at only 4.95 mm, while the tangential direction offers superior compressibility and thermal ...

Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

Archaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

GPU-Accelerated Signal Processing for Passive Bistatic Radar

Remote Sensing, 2023
Passive bistatic radar is a novel radar technology that passively detects targets without actively emitting signals. Since passive bistatic radar entails larger data volumes and computations compared to traditional active radiation radar, the development

2D/2D/2D Metallic 1T Phase WS2/TiO2/Ti3C2Tx MXene Ternary Composite for Synergistically Enhanced N2 Electroreduction

EcoEnergy, EarlyView.
TiO2 nanosheets were in situ grown on Ti3C2Tx MXene, and then 1T phase WS2 was distributed on TiO2/Ti3C2Tx MXene to form 1T‐WS2/TiO2/Ti3C2Tx MXene, which exhibits a prominent NH3 yield of 46.27 μg h−1 mg−1cat. at −0.8 V versus RHE and a superior FE of 69.26% at −0.65 V versus RHE.
