HALO, developed by BAE Systems uses multiple acoustic sensors and precise meteorological monitoring and terrain data to locate and identify artillery or mortar sources, as well as IED explosions.
The system can detect hostile firing near to adjacent friendly forces and identify areas of intensive activities. By detecting the occurrence of explosions of mortar fires, launching of RPGs or improvised rockets, sniper attacks and other gunshots, HALO automatically defines an area assigned with more attention from aerial and ground surveillance, ambushes and patrols.
HALO covers large areas (typically over 2,000 square kilometers) and rapidly determines fire sources with with location accuracy of 50-100 meters, by analyzing the acoustic propagation of the target’s signatures. HALO has been successfully deployed in combat zones including Bosnia, Kosovo Iraq and Afghanistan.
