07/30/2002 - Sharpshooters Get High Tech Help

Sharpshooters using high-powered weaponry will soon have a high tech target to help their quest for accuracy. Dave Saulibio, principal of DAS Electronics, has exclusive license to manufacture and distribute a newly invented high tech target. DAS Electronics has received a SIRTI commercialization grant and is a tenant in SIRTI’s business incubator. The target is still in prototype stage, but all design work, manufacturing, and marketing will be done in Spokane.

The seeming simplicity of the target belies the underlying engineering. The target has four acoustic microphones arranged in a diamond shape. The microphones are paired so that they are on an X – Y-axis, with the microphones facing outward toward the shooter. When bullets travel at supersonic speed, they create a shockwave just like a jet plane that breaks the sound barrier. The shockwave travels ahead, and the “normal” sound waves lag behind. The target’s microphones pick up the shockwaves that produce a discrete ‘signature’ that is very accurate because there is no noise distortion. It is a clean signature.

The target system measures time and distance within the X - Y-axis, pinpointing the accurate location of the bullet through the target. The microphones are connected to a special transmitter that sends the data back to a laptop computer with software available that is capable of receiving and interpreting the data. This means that the shooter doesn’t have to stop practicing to retrieve a paper target that may be more than 200 yards distant to assess accuracy. The high-tech target is more accurate and saves both time and trees.

The high tech target will be an especially valuable tool for police and military applications.
