Abstract
This paper briefly describes the set-up of the sensors and the instrumentation deployed by the French-German Research Institute of Saint-Louis (ISL) during the last NATO/ACG3/SG2 HFI Threat Data Collection (trial conducted during the summer 2014 in the Czech Republic). Measurements of acoustic signals generated by small-caliber weapons, ammunition, and rockets were carried out for the development of Hostile Fire Indicator (HFI) systems. For ground bases, imaging systems were associated with acoustic sensors in order to provide complementary information and better permanent surveillance / sniper detection. Our basic approach is to combine several technologies developed at ISL: acoustic detection, fusion of distributed sensor data, active imaging and 3D audio restitution of the threat.
