Abstract:
Acoustic surveillance of the battlefield enables the detection, classification, localisation and tracking of sound sources of military interest including ground vehicles, air vehicles and weapon fire. An application of current interest is the detection and localisation of sources of ground-based indirect weapon fire (from mortars and artillery) using acoustic sensors onboard a tactical unmanned aerial vehicle. The acoustic self-noise environment onboard an aerial vehicle is dominated by propulsion engine noise with air flow noise contributing to a lesser extent. By applying suitable signal processing and pattern recognition methods, it is shown that a tactical unmanned aerial vehicle can provide an effective platform for locating sources of indirect weapon fire.
