Acoustic Array Close-Range Rotor Acoustic Recognition System Drone Acoustic Signature Detection Systems
Product Overview
The Acoustic Array Close-Range Rotor Acoustic Recognition System is a specialized device dedicated to close-range acoustic detection and identification of "low, slow, and small" (LSS) targets—primarily UAVs—within low-altitude airspace.
Leveraging a high-sensitivity acoustic sensor array and advanced acoustic fingerprint recognition algorithms, the system captures the characteristic acoustic signatures generated by UAV rotor blades to achieve precise identification, range estimation, type classification, and real-time alerting of low-altitude airborne targets. Operating independently of optical or RF detection, it can function as a standalone solution or be seamlessly integrated into broader low-altitude defense architectures.
The system fills the critical gap in close-range acoustic identification of low-altitude targets and is widely deployed in airports, sensitive facilities, major event venues, and key security areas, delivering a cost-effective, highly reliable acoustic identification solution for low-altitude security and surveillance.
