DTIC ADA478974: Latest Achievements in Gunfire Detection Systems

For more than fifteen years, 01dB-METRAVIB has been carrying out many research and development activities in battlefield acoustics. In this article, we present our latest achievements in the particular domain of Gunfire Detection Systems (GDS). These systems are essentially based on acoustic detection with specific signal processing of Shock Waves and Muzzle Blasts. Their purpose is to detect and locate sniper and small-arms fire. The main parameters, which are estimated by these systems, are azimuth, elevation and range of the origin of a shot. These classical acoustic sensors can also be associated with other sensors, such as optical systems, thermal cameras, and LASER systems, etc. The latest on-going developments in 01dB-METRAVIB Gunfire Detection Systems are the following: (1) New systems with more than two acoustic arrays, (2) Specific data fusion and battlefield-oriented displays, (3) New wireless systems with radio devices, (4) New systems coupled with daylight and/or thermal cameras, (5) Original system allowing for specific detection mode, and (6) Other associated sensors. After a short overview of state of the art systems performances, we present these new systems with a
