The Radiometric Measurement Quantity for SAR Images [PDF]
A Synthetic Aperture Radar (SAR) system measures among other quantities the terrain radar reflectivity. After image calibration, the pixel intensities are commonly expressed in terms of radar cross sections (for point targets) or as backscatter ...

A golden age for spaceborne SAR systems [PDF]
Spaceborne Synthetic Aperture Radar (SAR) is the only imaging sensor technology that can provide all-weather, day-and-night and high-resolution images on a global scale. Today, SAR data are used for a multitude of applications ranging from geoscience and climate change research, environmental monitoring, 2-D and 3-D mapping, change detection, 4-D ...

A Phase Synchronization Method for Miniature Multistatic FMCW SAR
The miniature multistatic Synthetic Aperture Radar (SAR) system uses a flexible configuration of transceiver division compared with the miniature monostatic SAR system, thereby affording the advantages of multi-angle imaging. As the transceiver-separated

Biophysical approaches for studying viral entry
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
