    Default Anti - Sniper










    "Being shot at and never knowing where it comes from is a sure sign of a sniper. So BBN has come up with a solution. It’s called the Boomerang Mobile Shooter Detection System and alerts soldiers of incoming sniper fire to give them the opportunity to retreat to safety. Using seven microphones to detect both the muzzle blast and the shock wave from a speeding bullet. Once a sniper’s bullet is detected, it alerts soldiers through audio and visual signals that a bullet has been fired its direction and elevation.Snipers are going to get extra sneaky with this "

    Boomerang is a gunfire locator developed by DARPA and BBN Technologies primarily for use against snipers on mobile vehicles such as the Humvee, Stryker, and MRAP combat vehicles. There were future plans to integrate it into the Land Warrior system.

    Development
    Boomerang grew out of a program conceived by the U.S. Department of Defense in late 2003, months after the traditional combat phase of the Iraq War had ended on May 1, at a time when it was clear that U.S. troops were increasingly at risk from a growing and aggressive insurgency. Often, troops in noisy Humvees did not know they were being shot at until someone was hit. U.S. Defense Secretary Donald Rumsfeld approached DARPA and asked for near-term solutions that could be applied to the conflict in Iraq. Rumsfeld was looking for something that did not have to be a perfect solution, but was at least better than nothing

    The U.S. Army and Special Operations Command began using a limited number of French-made PILAR anti-sniper systems in 2003, but at $65,000 per copy was too expensive to field in great quantities. This led DARPA to develop a new, more affordable system. Karen Wood, a program manager at DARPA, said BBN's previous work was the most impressive that was examined. BBN had previously developed a less sophisticated counter sniper system named "Bullet Ears" under DARPA sponsorship in 1997.

    The new requirements included:
    Shooter localization to plus or minus 15 degree accuracy, and within one second of the shot
    Reliability for shot miss distances of one to 30 meters
    Ability to detect and localize fire from AK-47s and other small arms at ranges from 50 to 150 meters
    Reliable performance in urban environments with low buildings
    Operable when mounted on a vehicle moving up to 60 miles per hour on either rough terrain or highways
    Ability to withstand sand, pebbles, rain, and light foliage impacts
    Ability to deliver alert information in both a voice announcement and on an LED display
    Microphone array and electronics box must be replaceable in the field

    The first prototype was developed in 65 days. Challenges to overcome were filtering out noise from the vehicle on which it is mounted (such as loud engines and static sounds from the radio), ignoring sounds similar to that of a gunshot (such as fireworks or a car back-firing), factoring in bullet ricochets, and ignoring outgoing fire from friendly troops. Small quantities of Boomerang were battle tested in Iraq and further improvements lead to 2nd and 3rd generation versions called the Boomerang II and Boomerang III. In June 2008 a $73.8 million firm fixed price contract was awarded by the U.S. Army to BBN for 8,131 Boomerang Systems, spares and training services.
    In 2005 Boomerang won both the DARPA “Significant Technical Achievement Award” and the Massachusetts Innovation and Technology Exchange (MITX) "Technology Influencer of the Year Award."

    Operation
    The Boomerang unit attaches on a mast to the rear of a vehicle and uses an array of seven small microphone sensors. The sensors detect and measure both the muzzle blast and the supersonic shock wave from a supersonic bullet traveling through the air (and so is ineffective against sub-sonic ammunition). Each microphone detects the sound at slightly different times. Boomerang then uses sophisticated algorithms to compute the direction a bullet is coming from, distance above the ground and range to the shooter in less than one second. Users receive simultaneous visual and auditory information on the point of fire from an LED 12-hour clock image display panel and speaker mounted inside the vehicle. For example, if someone is firing from the rear, the system announces "Shot, 6 o'clock", an LED illuminates at the 6 o'clock position, and the computer tells the user the shooter's range, elevation, and azimuth.
    Boomerang works in extreme weather, in open field and in urban environments, whether static or moving. BBN states that false shot detections are less than one per thousand hours of system operation at vehicle speeds under 50 miles per hour.
