The military has high-tech equipment to track sniper fire, using microphones carried by soldiers or stationary mics mounted at strategic points. Now that technology is getting shrunk so it can be used in the hands of civilian bodyguards with Android phones.
A team of computer engineers from Vanderbilt University, led by Akos Ledeczi, has developed an inexpensive piece of hardware and related software to turn an Android smartphone into a sniper finder. The Vanderbilt team described the new system at the 12th Association for Computing Machinery/IEEE Conference on Information Processing in Sensor Networks in Philadelphia earlier this month.
