Saudi Arabian company reveals GBDF shot-detection system

22 February 2019

Saudi Arabia's Warning and Defence for Electronics Industries Co (WDEI) has developed a new shot-detection system - the Gun Blast Direction Finder (GBDF) - and displayed it at the IDEX 2019 exhibition in Abu Dhabi in February.The aerodynamic GBDF from WDEI displayed at IDEX 2019.

The GBDF is an acoustic system for detecting and locating the origin of small arms fire, using embedded algorithms to compute a shot source in horizontal and vertical planes. It provides 360° coverage horizontal and -15° to 45° vertical, with an accuracy of up to ±3° and a detection range of 2,400 m. The response time is "in milliseconds", according to WDEI.

The system consists of a four-microphone array with an aerodynamic design that a WDEI representative told Jane's was specifically intended to make it suitable for mounting on civilian transport, such as VIP limousines, or on armoured fighting vehicles. The microphone unit weighs 2 kg and can either be powered through a DC connection or by rechargeable batteries, with the latter having a 20-hour operating life. It can also be mounted on a tripod for static use.
