FMCW Lidar Beyond Nyquist by Instantaneous Frequency Fitting

This collection of recent wireless, sensing, and edge-AI research introduces multiple advances that have dual-use security implications. Papers describe methods that extend FMCW lidar range beyond Nyquist, improve robustness to phase noise (relevant to spoofing/resilience), new waveforms (WHTDM) and OTFS phase-noise estimation (impacting comms reliability), analog RF computing and MU‑MIMO inference (novel physical-layer computation with potential for covert channels or unintended broadcast of model weights), Rydberg-atomic sensor noise-mitigation (sensor hardening but also potential for novel監
