自90年代中期首次出现以来，执法机构一直在部署枪击检测系统，试图减少犯罪率高的城市地区非法使用枪支的情况。随着各机构寻求获得关于公共场所枪击事件的更好的实时地理空间信息，这种技术的使用已经普及，尽管这些系统的性能和可靠性仍然是一个活跃的研究领域。本文回顾了枪声的基本物理和枪声的发声机制，总结了枪声检测研究的历史，并调查了已发表的有关商业系统的技术和性能信息。Language：en
Since their first appearance in the mid-nineties, gunshot detection systems have been deployed by law enforcement agencies attempting to reduce the illegal use of firearms in highcrime urban areas. The use of this technology has spread as agencies seek to obtain better real-time geospatial information on gunshots in public spaces, although the performance and reliability of these systems is still an active research area. This paper reviews the basic physics of gunshots and the sound production mechanism of gunfire, summarizes the history of gunshot detection research, and surveys the published technical and performance information regarding commercial systems.
