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 and Mortars (RAM) and Small Arms Fire (SAF). The powerful signal processor embedded in the 2D sensitive AMMS is capable of analysing and localising acoustic signatures and reporting 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 allows the user to make use of a Digital Data Port Adapter (DDPA) such as a digital antenna. The dedicated Sensor Management System (SMS) enables the full employment of a multi AMMS network.
The AMMS uses Acoustic Vector Sensors (AVS), which simultaneously measure the amplitude and direction of sound events, rather than a standard microphone that only senses pressure. Due to this, and in combination with the powerful signal processor embedded in the AMMS, a single sensor can detect, classify, and determine the direction of arrival (DOA) of acoustical events of interest. By combining the information of multiple AMMS in a network, it is possible to triangulate the location of RAM and SAF with high accuracy, and with a low false alarm rate.
