Microflown Avisa

Microflown Avisa is a Dutch defence technology company specialising in passive acoustic vector sensing systems for battlefield and maritime situational awareness. The company develops advanced sensor solutions capable of detecting, locating, tracking and classifying threats such as drones, small arms fire, artillery, vehicles and helicopters using acoustic particle velocity technology rather than traditional radar systems. Their systems are lightweight, low-power, difficult to detect, and effective in all-weather and low-visibility environments, making them highly suitable for modern defence and security operations.
