Astiron Sentry
Passive acoustic sensing of micro-drones with zero RF emissions.
Microphone-array acoustic signature sensing that detects low-RCS drones before radar line-of-sight without revealing sensor positions.
Astiron Sentry utilizes multi-channel microphone arrays and edge signal processing to detect the acoustic signatures of drone motors and propellers. Because it is completely passive and transmits no radio emissions, it remains undetectable to hostile electronic surveillance while providing early bearing cueing against low-altitude and RF-silent aerial incursions.
Engineered for sovereign isolation and contested warfare.
Every component is architected from first principles to operate without reliance on commercial cloud providers or external connectivity.
Zero-Emission Stealth Operation
Emits no radio frequency signals or electromagnetic radiation, ensuring forward perimeter sensors remain completely covert.
Rotor Signature Classification
Separates distinct motor and propeller harmonic frequencies from ambient background environmental noise and wind turbulence.
Early Cueing Network
Triangulates acoustic arrival times to estimate target bearing and range, handing off coordinates directly to optical tracking nodes.
Signal-to-Decision Sequence
Continuous Passive Monitoring
Microphone array continuously samples ambient acoustic spectra across perimeter surveillance sectors.
Acoustic Tonal Filtering
Edge DSP isolates propeller harmonics and compares signals against calibrated aerodynamic signature profiles.
Cueing & Alert Hand-Off
Computes spatial bearing angle and pushes real-time alert vector to command consoles and optical turrets.
