Rheinmetall AG announced today that its active shooter detection system is ready for prime time. If  it proves to be reliable, the new detection system will add another level of security to the FOB as well as mechanized and foot patrols. Rheinmetall’s active shooter detection system is able to pinpoint threats, acoustic reconnaissance is an important capability for  warding off attacks of this kind. Acoustic reconnaissance components  significantly enhance the survivability and operational effectiveness of  command, mission-specific and combat vehicles deployed in high-threat  environments.

This led Rheinmetall to develop the Acoustic Shooter  Locating System (ASLS), a first basic version of which is now ready for the  market.

The ASLS basic version comprises a powerful acoustic sensor  platform (microphone antenna) with integrated analysis electronics as well as a  control and display device inside the vehicle.

When a shot is fired, the  ASLS alerts the crew acoustically and visually, instantly displaying the results  of the shooter location process on the control and display device, including  azimuth, elevation and distance. In addition, the shooter’s georeferenced  position is determined with a GPS system. This makes it possible to use the  information in C4I systems, e.g. for target assignment and subsequent  engagement.

The microphones feature an extensive dynamic operating range,  meaning that 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, meaning that the shooter’s position on the  control and display device can be precisely located even when the vehicle is on  the move. Furthermore, the display incorporates a history feature that enables  ready access to recent events.

An easy-to-use menu enables intuitive  operation of the ASLS after minimal instruction. Designed for compactness, the  ASLS is characterized by low weight and low power consumption (less than two  watts).

The basic configuration of the ASLS now available is designed for  maximum flexibility. A quick mounting device eliminates the need for a  vehicle-specific installation kit. This means that the system can be mounted in  less than 15 minutes even in small vehicles with very little effort. The  analysis electronics and battery pack are both integrated into the antenna base,  enabling the system to operate without being connected to the vehicle’s central  power supply. The analysis results can be transmitted to the control and display  device either by wireless link or cable.

The ASLS’s modularity assures  high growth potential. Numerous enhancements and integration solutions in  higher-echelon system environments are currently being examined under the rubric  of future technologies.
