The detection and localization of artillery guns on the battlefield is envisaged by means of acoustic aerial waves including sonic and infrasonic waves. The main objective of this work is to examine the different frequency ranges usable for the detection of an artillery gun on the battlefield and in particular to investigate the potential interest of the infrasound range. The main stages of this study have consisted of:
- data acquisition of acoustic (including the infrasound range) signals of artillery guns and mortars,
- modeling of the wave propagation in the atmosphere,
- signal processing and evaluation of the performance of a system of networked sensors.
Within the framework of the NATO AC 323 / RTO TG 25 group, relating to advanced concepts of acoustic and seismic technology for military applications, Technical Establishment of Bourges welcomed and organized a joint campaign of experiment intending to demonstrate the interest of a networked unattented ground sensors for vehicles detection and tracking in an area defense context. Having reminded the principle of vehicles tracking, this paper describes the
progress of the test campaign and details particularly sensors and participants deployment, the solution of interoperability chosen by the group and the instrumentation used to acquire, network, process and publish in real-time data available during the test: meteorological data, trajectography data and targets detection reports data. Finally, some results of the campaign are presented.
