Executive Summary
Battlefield Acoustic Sensor Network: 150 distributed acoustic sensor stations covering border regions and likely engagement areas. Functions: artillery localization (shells, rockets, mortars), drone acoustic detection, vehicle movement monitoring, gunfire detection. Integration with counter-battery radar for sensor fusion. Processing: AI-enabled acoustic classification. Target: 10km artillery localization, 5km drone detection, 95% classification accuracy.
In short: 150 acoustic sensor stations; 10km artillery localization (50m accuracy); 5km drone detection range
The Problem
Ukrainian counter-battery lesson: radar is excellent but jammable—Russian EW regularly degrades radar performance. Acoustic sensors passive, unjammable, detect what radar cannot. Ukrainian artillery officer: 'When radar was jammed, acoustic arrays still worked. They can't jam sound.' Artillery localization: acoustic triangulation pinpoints firing position within 50m at 20km range. Drone detection: propeller acoustic signature detectable before visual or radar contact. Current Lithuanian sensor coverage: radar-centric, single point of failure. Enemy knows to jam radar; acoustic provides backup and complement. Passive sensors: reveal nothing about own position, work continuously.
