Muzzle Flash Detection

Many conflicts and even peacekeeping operations are increasingly conducted in urban environments where attacks can come from any direction and elevation.  The majority of engagements occur at distances of 100m or less with multiple shots being fired per second. In these environments, soldiers have no technology to help them to identify the location of an enemy shooter. 

 

The best available products are based on acoustic sensing, a technology that has two crippling weaknesses for gunfire detection.  It is unreliable in cluttered environments due to sound reflections and struggles to distinguish more than a single shot per second.  

 

The optical solutions that are available provide the precise location of gunfire but are prohibitively expensive and have not been adopted at scale.  They are orders of magnitude too big to be used by an individual soldier.

The next generation of shooter detection 

Tethir has a solution capable of detecting the location of a muzzle flash and displaying it for soldiers almost instantly.  Innovative optics enable a sensor that has comparable performance to the highest precision devices and is affordable to deploy at scale.

System attributes:

  • 360-degree x 90-degree field of view, a 4X improvement over current optical detectors. 

  • Detection rate up to 1,800,000 shots per second, which in practical terms means all shots in line-of-sight of the detector will be detected.

  • Component cost 20X times lower than those in current infrared gunfire sensing products. 

  • 20cm x 20cm x 20cm or smaller for the full 360 degree FoV, equivalent to 8 times smaller than current devices, which only have a 90 degree FoV.

Applications

​The device is first being developed for vehicles and stationary applications, with plans for further adaptation and miniaturisation to achieve a device capable of being used by individual soldiers. 

 

Wider applications include: 

  • Unmanned Aerial Vehicles (UAV) (tethered or otherwise). 

  • Unmanned Ground Vehicles (UGVs).   

  • Fixed site protection for FOBs (Forward Operation Bases) and checkpoints

  • High-risk border crossings

  • Protection of VIPs in open public space

The full potential 

Optical detection of a muzzle flash allows for categorisation by caliber or even weapon type and the detectors can be optimised for the detection of specific weapons.  For example, the distinct signature of a 7.62×39 mm round fired by the AK-47 can be used to optimize the system to achieve the highest reliability for the detection of this and similar weapons.
