Tiny Sensor Listens For Gunshots, Identifying The Gun and Location

[Marxist]

This is the gear that gets our troops excited. Microflown Technologies' tiny sensor listens for the sounds of war by measuring particles in the air. Then it reports what weapon made the sound and where that sound originated.

The sensor uses a technology, developed by Microflown, called acoustic vector sensing. AVS heats two 200-nanometer wide platinum strips to 200 degrees Celsius and measures how passing air particles cool them down. From those cooling patterns, Microflown's proprietary software can determine not only what the sound is but also where it came from.

There are other technologies that can do the same type of thing, but they all have their own unique disadvantages: radar-based solutions are traceable; others require the deployment of large apparatuses, and some need multiple sensors to triangulate sounds.

Microflown's matchstick almost seems too good to be true, but several nations' armies—including the Netherlands, Germany, India, Poland, and Australia—are currently testing out the tech and seeing what they hear

Microflown Technologies manufactures unique and patented source (target) locating sensors for the defence industry, enhancing situational awareness. The breakthrough acoustic particle velocity sensors are used as extremely compact (5mm&#179 acoustic vector sensors (AVS), capable of detecting, localising, identifying and tracking sound sources in 3D space. AVS can be deployed on a variety of platforms, be it on land, in the air or at sea.

Sniper / gunshot detection system

Developed for the protection of personnel in hostile environments, Microflown’s sniper detection system detects and localises hostile gunfire using compact acoustic vector sensors (AVS). Incoming supersonic projectiles trigger the detection software with both the supersonic shockwave and subsequent muzzle blast being measured. With a single AVS, all of the relevant information including bearing, elevation and range of the shooter are calculated and reported.

The sensors are ground deployable in either mobile or semi-permanent locations. The integrated 3D compass and inertial sensors allow the system to be deployed with minimal set-up time. In a networked configuration, the calculated sniper locations are sent to command & control.

In addition, the sensors can also be vehicle mounted for gunshot detection on the move. Vehicle-mounted versions include a visual display with audio reporting inside the vehicle.

Artillery detection systems

Microflown’s artillery detection system uses AVS to detect and localise gun breaks and impacts from artillery guns, mortars, tanks, heavy cannons as well as explosions from mines, bombs and improvised explosive devices (IEDs). With a single sensor unit, bearing and elevation are calculated. In a networked configuration, range is also calculated with all data being sent to command and control.

As with Microflown’s sniper detection system, the sensors are available as ground sensors or vehicle mounted sensors. The 3D compass and inertial sensors allow minimal set-up time.

These ‘acoustic radars’ can be complimentary to weapon locating radar (WLR) systems as they work in close range and under unfavourable weather conditions such as fog or rain. They can be used for filling in acoustic gaps, cueing the radar where to look, and confirming the targets acquired by the WLR.

Shooting range acoustic scoring system

The same technology used in Microflown’s sniper detection system is used to detect supersonic projectiles as they hit, or pass near to, targets. With just two acoustic vector sensors positioned next to the target, the system can calculate the position of the projectile and compare this against the known target position. The shooters ‘score’ is displayed on a score computer, and can be saved for further analysis and statistics.

Microflown’s Shooting Range Acoustic Scoring System can be used for all supersonic projectiles fired on pistol and rifle ranges, tank and other direct fire artillery ranges and air to ground shooting ranges.

Border / perimeter control radar systems

Microflown’s border / perimeter control is a passive ‘radar’ system using acoustic signals to detect, localise, classify and track aerial and ground vehicles. Multiple sensor units can be installed along the border or perimeter to be protected, with a spacing of around 10km.

One or more acoustic vector sensors can detect a threat within a range of 10km (aerial) and around 2km (ground) and relay the information via radio communications to command and control. Within a few seconds the location of the threat and calculated trajectory is displayed to operators. Using the acoustic signature of the source, the threat can be identified as a helicopter, propeller airplane, jet, ground vehicle or boat. The threat data can be integrated into existing command & control systems to supplement a national or local common operating picture.

Additional applications include:

* Sense and avoid system for unmanned aerial vehicles (UAVs)
* Automated take-off and landing (ATOL) for UAVs
* Pirate warning system for sea vessels
* White-out / brown-out landing system for helicopters
* Acoustic beacon assisted parachute drops (targeting system)
* Underwater situational awareness
