3D acoustic situational awareness



Threat / end user issue

Forward operating bases and temporary camps do not have the infrastructural protective measures that main bases and/or permanent camps have. This makes these forward operating bases and temporary camps vulnerable to threats, such as small arms fire (SAF), mortar, artillery and rocket (RAM) attacks. An all-weather, day & night and non-line-of-sight situational awareness on such threats is essential for provision of effective protection.

Our solution

The Acoustic Compound Protection System (ACOMPRIS) offers a persistent and omnidirectional surveillance capability to detect and localize hostile direct and indirect fires. Using a network of sensor posts and a command post, it provides essential situational awareness by providing – in real-time – time-stamped and geo-referenced messages on positions of hostile firing locations and categorization of hostile fire. These messages are displayed on a map in the Microflown AVISA C2 ­application, or can be forwarded to a 3rd party application using a message interface.

Key characteristics

  • All weather, day and night, non-line-of-sight capability
  • Low SWaP, rapidly (re-)deployable, mobile
  • Passive, low observable
  • Requires no line of sight
  • Detection ranges up to 1800m (SAF) / 20km (RAM)
  • Suited for compounds of dimensions up to ~1 km2, scalable to larger dimensions
  • Operates as self-contained system, optional interfacing via message interface

How does it work?

The ACOMPRIS command post collects the muzzle blasts, shockwaves and impact explosions detected by the combined sensor posts in the network. It does so for singular (time separated) shots as well as for bursts and for simultaneous shots. Muzzle blasts, shockwaves and impact explosions are correlated, resulting in calculated hostile firing positions. These positions are plotted on a map display, visualizing location and category (SAF or RAM) of hostile fire, as well as which of the sensor posts contributed to the localization(s) made. All information is stored in the command post database and can be browsed and queried as needed.
