Detect and Neutralize Aerial Hidden Threats

ACU Labs develops acoustic intelligence systems to detect, localize, and neutralize fiber-optic UAV threats that conventional electronic sensors may miss.

MISSION

Fiber-optic drones operate without radio emissions. They cannot be detected, classified, or defeated by RF-centric counter-UAS systems. ACU Labs treats this gap as the next operational frontier.

  • PASSIVE DETECTION. Acoustic arrays identify rotor and propulsion signatures with no transmitted energy.
  • MULTI-NODE LOCALIZATION. Distributed sensor geometry resolves bearing and range without depending on the threat’s emissions.
  • THREAT INTERDICTION. Detection drives structured response — handoff to integrated effectors and downstream command & control.

CAPABILITIES

C-01

ACOUSTIC SIGNATURE ANALYSIS

Spectrogram-based classification of rotor harmonics, motor whine, and aerodynamic noise across the audible and near-ultrasonic band.

C-02

MULTI-SENSOR GEOMETRY

Four distributed nodes resolve bearing-of-arrival, with uncertainty bounds visualized in real time.

C-03

FIBER COUPLING RESEARCH

Investigation of acoustic-to-fiber coupling pathways using G657A2-class spools as candidate distributed sensing media.

C-04

EVIDENCE-GRADE LOGGING

Every detection event is timestamped, justified, and exportable as structured audit data for downstream review.

TECHNOLOGY

FIBERSENTRY ACOUSTIC

FiberSentry Acoustic is an operational acoustic C-UAS platform built around distributed fiber sensing, passive multi-node geometry, and signature-driven classification of fiber-optic UAV threats.

Deployable as a standalone four-node array or integrated into existing site-defense stacks, FiberSentry feeds classified detection events into downstream effector and C2 systems for end-to-end interdiction.
