Passive Low-Altitude Security
New Ark acoustic detection systems use passive microphone arrays and AI recognition to detect, classify, and localize UAV activity without transmitting electromagnetic signals.
Illustrative deployment scenario
A passive microphone-array node can add discreet awareness around logistics roads, warehouse edges, and selected asset boundaries. Acoustic indications may then be shared with visual verification workflows for operator review.
Every aircraft produces a characteristic acoustic signature. New Ark combines multi-array sound capture, direction-of-arrival processing, and trained acoustic classification to provide an early-warning layer for low-altitude security teams. The platform can be deployed as a single local sensor node or as part of a distributed acoustic fence.
Discuss acoustic detectionSystem capabilities
Detects acoustic signatures without active RF or radar emissions from the sensing node.
Classifies characteristic UAV sound patterns to support faster operator assessment.
Combines directional arrays for broad coverage and practical source-direction awareness.
Supports layered deployment with EO, thermal, AI tracking, and command-and-control workflows.
Applications
Acoustic detection can provide a discreet and scalable first layer in a wider low-altitude security architecture. New Ark works with integrators and operators on OEM, ODM, and site-adapted deployments.
Frequently asked questions
No. The sensing layer listens for characteristic sound patterns and does not require an active RF or radar emission from the microphone node.
Yes. Acoustic indications can support operator workflows with EO, thermal, AI tracking, or command-and-control systems.
Common civil applications include industrial parks, ports, energy facilities, airport perimeters, and protected outdoor sites.
