High-performance microphone array is innovatively developed to address the security threats posed by "black fly" UAVs such as racing drones and fiber optic racing drones, effectively solving the limitations of traditional radar and optoelectronic monitoring technologies (obvious low-altitude blind spots, high susceptibility to weather and light, low recognition rate for small targets). It accurately captures the dynamic acoustic signals of low-noise UAVs, realizing efficient early warning, high-precision positioning and real-time tracking, providing low-cost and reliable air defense security for sensitive areas such as airports, military management areas, large venues and core infrastructure. Below is the detailed parameter table and functional description:
