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
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
