Mission Statement

M transparenticroflown AVISA’s mission is to provide a complete 3D acoustic situational awareness:

By detecting, classifying, localising and (where applicable) tracking all sorts of audible threats, such as:

  • Small Arms Fire (SAF)
  • Rockets, Artillery and Mortars (RAM)
  • Aerial threats ( unmanned aerial vehicles, helicopters, airplanes and cruise missiles)

From all kinds of platforms:

  • Unattended Ground Sensors
  • Ground Vehicles
  • Unmanned Aerial Vehicles
  • Helicopters
  • Dismounted soldiers

 

Enabler

Enabler for Microflown AVISA is its proprietary acoustic sensor, the Microflown, the world’s first and only dedicated acoustic particle velocity sensor.

Acoustic Vector Sensor

Acoustic Vector Sensor

 

Any sound field can be completely described by two quantities:

  • Sound pressure
  • Acoustic particle velocity

If compared to the electrical domain:

  • sound pressure would be the equivalent of volt ( driving force)
  • acoustic particle velocity the equivalent of amperes ( the current)

The MEMS technology based sensor was invented in 1994 by Hans-Elias de Bree, co-founder of Microflown, at the University of Twente in Enschede, the Netherlands.

Responsible business

Microflown AVISA’s products and capabilities are used for anti poaching in Africa, protecting rhinos and elephants from being killed for unjustifiable reasons.
