Abstract

The detection of impulsive acoustic signals and their classification as gunshots plays a crucial role in systems designed to pinpoint the origin of gunshots fired by snipers or regular shooters. With significant applications in the military context, gunshot detection systems face substantial challenges related to their use in operational environments, which often involve multipath propagation and environmental noise. Moreover, these systems need to be capable of real-time operation. This article addresses modern methods for detecting and classifying the acoustic components of gunshot signals, proposing modifications to enhance their performance and evaluating them using a diverse dataset of real-life gunshot signals. The results are compared to determine the most suitable method for hardware implementation. The text provides valuable insights for developing gunshot detection systems in challenging environments.
