The briefing
Researchers adapt hybrid frequency‑domain CFAR detectors from radar to improve spectrum sensing in contested cognitive radio networks, showing strong performance against barrage and swept‑FM jamming. The study also flags a dual‑use risk and proposes an algorithm‑aware countermeasure that can disrupt unauthorized use while preserving primary‑user detection.
