Sensor Element

The Acoustic Vector Sensor (AVS) technology is embedded in the Acoustic Pointer as a 3D sensor. The AVS can detect, classify and locate all sorts of acoustic events in 3D space, e.g: Small Arms Fire (SAF), Rockets, Artillery and Mortars (RAM),  tonal sound sources (ground vehicles, fixed wing aircraft, and helicopters).

At any point in space, a sound field can be described completely by its two dimensions: the scalar value  and the vector value.
The scalar value, sound pressure, is well known and well measured. On the other hand, the other quantity in acoustics (Acoustic Particle Velocity) recently became a directly measurable quantity with the invention of the Acoustic Vector Sensor (AVS) by Microflown AVISA.

The extremely small and light-weight Acoustic Vector Sensor is capable of detecting, localising, identifying and tracking sound sources in 3D space.
With this unique technology multiple sources can be located simultaneously even in complex situations such as urban environments or on noisy platforms such as UAVs and ground vehicles.
