Hostile Fire Indicator threat data collection for helicopter-mounted applications

摘要

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 PROTEUS which has been conducted during the summer 2012 in Slovenia). The main purpose of this trial was the measurements of weapon and ammunition signatures for threat warning and hostile fire indicator (HFI) system development. The used weapons vary from small caliber rifles to anti-tank rockets in ground-to-ground shooting configurations. For the ISL team, the objectives consisted in measuring the acoustic signals for detection and localization of weapon firing events. Experimental results of sound localization obtained by using ground based sensors are presented and analyzed under various conditions.
