Radio-frequency counter-drone engine detects uncataloged emissionsNewsDan Taylor Technology Editor Military Embedded SystemsRfAI-3 display via DroneShieldSYDNEY, Australia. DroneShield unveiled RfAI-3, a radio-frequency counter-drone detection engine designed to identify both known and previously uncataloged drone emissions, the company announced in a statement. The system monitors a wide section of the radio-frequency (RF) spectrum rather than searching only for signals already stored in an emitter database, the statement reads. When RfAI-3 detects a signal, it compares the emission with previously collected drone signatures and provides classification data when a match is found, the company says. The software is intended for DroneShield’s next-generation hardware platforms, with initial releases planned for the second half of 2026 and additional deployments expected through 2027, the statement reads.
