Small Arms Fire (SAF)

Acoustic Multi-Mission Sensors (AMMSs) can be used to detect and locate Small Arms Fire (SAF), either operating as a single sensor or in a networked mode.

Supersonic bullets create both, a shockwave and a muzzle blast.

The shock-wave provides an alert and a sector area where the shot was fired from.

If the muzzle blast is captured as well, the location can be determined with:

• an angular accuracy of 5 degrees
• a range accuracy of ±20%

An interesting feature of the AMMS is that is it is also able to locate shooters that are not necessarily aiming on the sensor node itself.

Even if the closest point of approach (CPA) of the bullet is up to 500 meters, a single AMMS is able to derive the shooter position.

Hence, the range of the so called Acoustic Umbrella is high.
