Bend the beam like Beckham to defeat anti-jamming tech

Rice University researchers demonstrated a proof-of-concept jamming technique that uses self-curving radio beams to fool direction-of-arrival (DoA) estimators, preventing conventional DoA-based anti-jamming defenses from reliably locating or blocking the jammer. The lab results show catastrophic bit-error-rate degradation and the ability to create the illusion of a moving jammer from a stationary transmitter, highlighting potential risks to systems that rely on DoA for mitigation (for example GPS receivers), though no active exploitation is reported.
