MIKES gunshot detection system prototype

In this paper, a gunshot detection system prototype designed and produced in MİKES Inc., will be mentioned. The system has five subsystems, a reference microphone unit, a central unit and a user computer. Although 26 microphones are employed in the prototype, the system hardware background supports synchronous processing of 256 microphone data. Each subsystem on its own has the capability of finding the direction of the shot. The system together can find the location of the shot. The algorithm employed in the system for localization is TDOA based. The resistance of the system against TDOA errors is simulated through MATLAB. The system is distributed over an area, tested and verified by real-time experiments.
