Deep Sigma Point Processes for RCS Modeling in Spaceborne SAR Imagery

This document is an arXiv feed containing newly announced research on signal processing, wireless communications, radar and SAR modeling, O-RAN/5G vehicular networking, medical imaging, and measurement systems. The works are methodological and do not describe software vulnerabilities, exploits, malicious activity, or security incidents. Some topics have security relevance—such as satellite-terrestrial interference mitigation, O-RAN machine learning, radar-based ship modeling, and communications robustness—but no specific cybersecurity threat or vulnerability is identified.
