SIRENS – Signal Interference cancellation using REconfigurable iNtelligent Surfaces

Communication systems for unmanned ground and air vehicles often face critical challenges from jamming, spoofing, and eavesdropping, especially in highly dynamic and electromagnetically disturbed environments. SIRENS uses Reconfigurable Intelligent Surfaces (RIS) to create high-SNR paths securing links despite LoS blockages and generate safe “bubbles” to neutralize jammers/spoofers and form low-SNR dead zones around eavesdroppers. Sensing RIS detect and localize threats, enabling targeted countermeasures with multi-frequency and solar-powered, remote-controlled deployment.
