Learning Compact Terrain-Context Representations for Feasibility-Aware Offline Reinforcement Learning in UAV Relaying Networks

This collection of papers presents advances in wireless communications, sensing, and learning that have dual-use security implications. Highlights: RFSS — a publicly released 103 GB 3GPP-compliant multi-source RF signal separation dataset (GSM/UMTS/LTE/5G NR) with benchmarks, which can accelerate development of powerful source-separation and interception tools; 6G BI-SAR/BI-ISAR imaging methods that perform high-resolution imaging using Doppler-only processing (privacy/surveillance risk); multiple ISAC, antenna and RIS advances (SWAN pinching-antenna CRLB optimization, scalable fluid-antenna S
