Gunshot Acoustic Detection Arrays, Drone RF Sniffing and Direction-of-Arrival (DoA) Estimation

Secondary surveillance arrays detecting airborne drone control signals, illegal radio transmissions, and acoustic fence cutting.

Software-Defined Radio (SDR) Drone Detection

An integrated wideband SDR scans ISM bands (915 MHz, 2.4 GHz, 5.8 GHz) for protocol signatures of unauthorized commercial drones, measuring signal strength and bearing to alert air defense personnel.

Acoustic Perimeter Breach Identification

Four directional microphones analyze ambient environmental sounds, utilizing wavelet transformation to isolate acoustic signatures of angle grinders, chain-link fence clippers, and vehicle engines.

70 MHz to 6 GHz wideband SDR scanning drone telemetry protocols
Acoustic Direction-of-Arrival (DoA) accuracy within ±2 degrees
Instant classification of fence cutting, vehicle idling, and gunshots
Zero RF emissions during silent passive listening mode
