The point spread function for UWB SAR imaging using inversion of the circular radon transform

, 2004
This paper summarises how SAR data collection can be viewed as taking the Circular Radon Transform of the ground reflectivity and outlines how image formation can be achieved by inverting the CRT via a Fourier-Hankel transform.

Tuning Pore Geometry of Zirconium Metal–Organic Frameworks via Bent Ligands for Enhanced Sulfide Oxidation Catalysis

Angewandte Chemie International Edition, EarlyView.
Engineering pore geometry through ligand conformational bending enhances active‐site accessibility and mass transport in Zr‐MOFs, leading to superior catalytic sulfide oxidation. ABSTRACT Pore engineering represents a powerful strategy to tailor the physicochemical properties of metal–organic frameworks (MOFs), yet the structure‐activity relationship ...

Compositionally Engineered Carboxymethyl Cellulose‐Based Optical Fibers With Exceptionally Low Optical Loss and Quantitative Humidity Sensing

Advanced Physics Research, EarlyView.
Carboxymethyl cellulose‐based biopolymer optical fibers are fabricated using aqueous wet spinning. The fibers exhibit record‐low optical attenuation in polysaccharide‐based waveguides while maintaining efficient transmission across the visible‐to‐near‐infrared region of the electromagnetic spectrum.

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 ...

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Investigating Pompeii Subsoil Using Geomatics and Geophysics Merged Analyses

Archaeological Prospection, EarlyView.
ABSTRACT The archaeological site of Pompeii represents an exceptional context for the application of non‐invasive and integrated investigation methods aimed at enhancing the understanding of both exposed and buried remains. This study presents the results of multidisciplinary research conducted in the Palestra Grande site, a large and strategically ...
