Emits nothing
A sensor that only listens gives away no position of its own.
Drones are heard before they are seen.
Sonous builds passive acoustic sensors that detect and locate small drones by sound alone.
Capability
Sound is the one signal that cannot be switched off.
Radar struggles with aircraft that fly small, low and slow. Radio detection needs a drone that transmits. We listen instead.
Hears the silent ones
Autonomous and fibre-optic drones carry no radio link. They still make noise.
Past the treeline
Sound travels around the terrain that stops a beam.
Mission
Earliest warning, for the people closest to the threat.
Equipment one person can carry, emplace and walk away from. Cheap enough to put everywhere it is needed.
