Optical Hostile Fire Source Sensor (OHFSS)
One of the fundamental tasks of forces operating on the battlefield is suppressing enemy fire.
In order to effectively engage sources of enemy fire, these sources must be detected and located, then pointed out to the combat element for the desired response.
On today’s battlefield, sources of enemy fire are difficult to pinpoint as they normally possess an extremely short life cycle. Enemy targets pop up, fire and promptly disappear to reemerge elsewhere.
Accordingly, combat elements require a system capable of detecting, locating and pointing hostile fire sources within a relevant time interval to enable effective response.
ACS presents OHFSS – Optical Hostile Fire Source Sensor.
OHFSS is a family of passive optical sensors designed specifically to detect and locate sources of hostile fire on the battlefield. The various OHFSS variants can detect and locate small arms fire, mortar fire, artillery fire, man-portable anti-tank rocket propelled grenade (RPG) launches, Anti-Tank Guided Missile (ATGM) launches and sniper fire.
The OHFSS unit provides an indication of the bearing to the fire source (azimuth and elevation) along with a classification of the threat. By combining multiple OHFSS units and using triangulation, hostile fire sources can be located very accurately.
OHFSS units may be installed as part of a self-protection system, where their function is to detect sources of incoming fire and trigger a responsive measure, or as a standalone detection system. Possible combinations include remotely-controlled weapon stations, soft-kill resources, command and control systems and active protection systems for armored vehicles.
