KIEL, Germany, July 27 (UPI) -- An acoustic system to pinpoint the originating location of enemy gunfire is being introduced by Rheinmetall of Germany.

The basic version of the Acoustic Shooter Locating System comprises a powerful acoustic sensor platform (microphone antenna) with integrated analysis electronics as well as a control and display device in the vehicle on which it is mounted.

When a shot is fired, the ASLS alerts the crew acoustically and visually, displaying the results of the shooter location process, including azimuth, elevation and distance, on the control and display device, the company said.

In addition, the shooter's position is determined with a Global Positioning System, making it possible to use information in C4I systems for target engagement.

Rheinmetall said the microphones feature an extensive dynamic operating range, meaning they reliably register loud artillery fire as well as less noisy muzzle blasts.

The optimized microphone antennas and robust signal analysis procedure enable precise location of the shooter, with complete coverage of the surrounding terrain and a low false alarm rate even in the disrupted zone around the vehicle.

Integrated position sensors compensate for the movement of the vehicle so the shooter's position on the control and display device can be precisely located even when the vehicle is on the move.
