IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.This article proposes a feedback node aided distributed spoofing (FNA‐DS) system, enabling flexible implementation of distributed spoofing. Field experiments using a self‐developed distributed spoofing prototype validate the FNA‐DS system's effectiveness and expose limitations in existing direction of arrival based anti‐spoofing techniques.
