Hostile Fire Locator - Counter Sniper

A radar-based solution to detect and locate hostile small arms fire

HFL-CS is a radar-based solution that provides automatic hostile fire detection and localization of the source of small arms fire, from 5.56mm caliber up to rocket propelled grenades. It calculates a projectile’s trajectory and in less than 3 seconds is able to locate the direction and range of the point of origin, as well as classify the type of threat by its caliber.

HFL-CS Radar

As HFL-CS is radar based, it overcomes some of the limitations of alternative acoustic solutions. It is unaffected by high background noise or acoustic echoes in urban environments and can be operated at night and in low visibility conditions such as smoke, dust, rain and fog.

HFL-CS is a modular system and can be configured to provide safety and protection in a fixed location or on the move mounted on a vehicle. It can also be integrated with an unmanned ground vehicle (UGV).

HFL-CS Applications

Civil & Military Protection
Protection of military or civilian convoys and fixed positions (such as forward operating bases)
VIP Protection
Protection of VIPs at public appearances
Public event security
Critical infrastructure
Protection of oil, gas and electricity facilities, dams and transport hubs

HFL-CS Gunshot detection radar Main Benefits

Superior performance-to-price ratio

Increases the level of safety for personnel and equipment

Lightweight and easy to deploy, transport and maintain

All weather operation, day and night and in low visibility conditions

Immune to battlefield and urban environment noises and echoes (unlike acoustic reliant systems)

Immune to silencers and cannot be deceived by sniper tactics, camouflage or equipment

Estimates POL and POI coordinates, allowing targeted countermeasures

High reliability (98% probability of detection and quasi-zero false alarms due to the use of purposely designed and built radar sensors)

Intrinsically multi-target

Estimates a projectile’s trajectory
