Paper Abstract

This paper provides a detailed analysis of the most specific parameters of gunshot signatures through models as well as through real data. The models for the different contributions to gunshot typical signature (shock and muzzle blast) are presented and used to discuss the variation of measured signatures over the different environmental conditions and shot configurations. The analysis is followed by a description of the performance requirements for gunshot detection systems, from sniper detection that was the main concern 10 years ago, to the new and more challenging conditions faced in today operations. The work presented examines the process of how systems are deployed and used as well as how the operational environment has changed. The main sources of false alarms and new threats such as RPGs and mortars that acoustic gunshot detection systems have to face today are also defined and discussed. Finally, different strategies for reducing false alarms are proposed based on the acoustic signatures. Different strategies are presented through various examples of specific missions ranging from vehicle protection to area protection. These strategies not only include recommendation on how to handle acoustic information for the best efficiency of the acoustic detector but also recommends some add-on sensors to enhance system overall performance.
