Acoustic Multi-Mission Sensor

The ground based AMMS utilizes the worldwide unique Acoustic Vector Sensor technology allowing it to detect, classify and localise the full spectrum of acoustic battlefield signatures such as Rockets, Artillery, Mortars  (RAM) and Small Arms Fire (SAF). The powerful signal processor embedded in AMMS is capable of analysing and localising the acoustic signatures and reports to the Battlefield Management System (BMS). The ground sensor‘s Digital Data Port interfaces with the customer specific hardware and BMS, supporting a variety of digital standards including the DAMA protocol. It also enables the user to make use of a Digital Data Port Adapter (DDPA) such as a digital antenna. The dedicated Sensor Management System (SMS) allows the full utilisation of a multi AMMS network.

Acoustic Multi-Mission Sensor

Based upon the Acoustic Vector Sensor, Microflown’s Acoustic Multi-Mission Sensor (AMMS) is a commercial off the shelf product combining both the SAF | Small Arms Fire signature, well as the RAM | Rocket Artillery Mortar signatures in one product. AMMS has shown extremely better performance for shooter localisation, both in terms:

  • the maximum distance between the shock-wave of the bullet passing by the sensor node
  • the accuracy, both in range and angle

The Acoustic Multi-Mission Sensor (AMMS) is a revolutionary acoustical detection system, capable of detecting and localising Rockets, Artillery and Mortars (RAM) and Small Arms Fire (SAF) in a single, compact system. The system uses Acoustic Vector Sensors (AVS), which simultaneously measure the amplitude and direction of sound events, rather than just sending pressure, such as a standard microphone. Due to this, a single sensor for the size of a pencil eraser can detect, classify, and determine the direction of arrival (DOA) of acoustical events of interest.

Since the AVS works with a board frequency range, it is possible to determine the direction of both mortars (low frequency) and small arms fire (higher frequency) with the very same individual sensor node. A single sensor can localise SAF (direction and distance) and RAM (direction only). By combining the information of multiple sensors, it is possible to triangle the location of RAM. When networked together AMMS is capable of localising both SAF and RAM events with even greater accuracy, a very low false alarm rate

The Royal Netherlands Army has been using AMMS since 2012, to acoustically localise RAM, and since 2013, also Small Arms Fire (SAF).

Novel Acoustic Multi-Mission Sensors (AMMS) are capable of detecting, localising and (where applicable) tracking all sorts of acoustic sound sources in 3D space such as:

  • Acoustic bursts/blasts, varying from Small Arms Fire (SAF) to Rockets, Artillery and Mortars (RAM)
  • Tonal sound sources like helicopters and ground vehicles

The AMMS utilises the worldwide unique Acoustic Vector Sensor technology allowing it to detect, classify and localise the full spectrum of acoustic battlefield signatures such as Mortars, RPGs and Small Arms Fire (SAF). The powerful signal processor embedded in the AMMS is capable of analysing and localising the acoustic signatures and reports to the Battlefield Management System (BMS). The AMMS‘s Digital Data Port interfaces with the customer specific hardware and BMS, supporting a variety of digital standards including the DAMA protocol. It also enables the user to make use of a Digital Data Port Adapter (DDPA) such as a digital antenna. The dedicated Sensor Management System (SMS) allows the full utilisation of a multi AMMS network.

The low Size, Weight and Power (SWaP) allows quick and easy deployment of a single AMMS to support forward observers, or multiple sensors networked to protect critical infrastructure, embassies, forward operating bases and/or combat outposts. The networked AMMS can also be operated in a RAM-SCORE configuration for target practicing or in a RAM-LOC configuration for theater or borderline use and can be utilised to cue cameras.

AMMS units can be operated from -20°C up to 70°C, in severe weather conditions with wind speeds up to 6BFT. The AMMS consumes less than 2 Watts and is mains powered. For safety purposes against potential IEDs the unattended ground sensor is equipped with an anti-tampering feature, reporting any abnormal activity to the BMS.

signatures

Both the SAF | Small Arms Fire signature, well as the RAM | Rocket Artillery Mortar signature, are available for incorporation in the AMMS.
