Presented at Brave1 Components Dec 2025. Uses phased-array microphones with bimodal beamforming — scans the sky with millions of acoustic 'beams'. FPV: 200–300 m targeting; Shahed-class: up to 5 km. Tested live during Shahed waves and cruise-missile launches. Hemispherical scan, multi-target, urban-noise-resilient. Designed for engagement, not just detection — outputs targeting-quality coordinates to automated weapon stations.
