Passive Acoustic Drone Localization | Detect RF-Silent Fiber FPV Drones Invisible to Radar & SIGINT

Radar and RF SIGINT systems struggle against fiber-optic FPV drones. These threats send no radio signals and are invisible to traditional radio-based C-UAS sensors. Our passive acoustic array solves this critical blind spot. 🔹 Fully passive design, ZERO electromagnetic emission. Your defensive site stays covert, no signal footprint to be detected by adversaries. 🔹 Works reliably under heavy electronic jamming & EW environments. Radio interference cannot disable acoustic detection. 🔹 Networked microphone array calculates real-time 3D position, azimuth and altitude of incoming drones. 🔹 Open API for seamless integration with your existing C-UAS stack: radar, SIGINT, EO/IR cameras, HPM or jamming countermeasures. 🔹 Available as finished units or PCBA modules. Sample evaluation kits ready for system integration and field tests. Acoustic sensing captures rotor noise — the one signature that silent FPV drones cannot eliminate. It complements, not replaces, your current radar and SIGINT systems. Build a complete layered low-altitude defence solution for critical infrastructure, border sites, refineries and military bases. If you are a C-UAS system integrator looking to fill the silent drone detection gap, contact us for datasheets, field test footage and sample details. #CUAS #CounterUAS #DroneDetection #AcousticDetection #PassiveSensor #FPVDrone #SilentFPV #UAVDefense #LowAltitudeSecurity #DroneLocalization #SIGINT #ElectronicWarfare #DroneThreat #CriticalInfrastructureSecurity #BorderSecurity #AntiDrone #UAS #DroneDefense #LayeredDefense #DroneSurveillance #RFJamming #HPM #EOIR #DroneEarlyWarning #PerimeterSecurity`
