Research on Individual Gunshots Localization Technology Based on Stabilized Fast Transversal Recursive Least Square Algorithm

In order to reduce noise interference and improve the localization accuracy, the individual gunshots localization technology under the condition of low SNR is studied. In this study, muzzle blast wave endpoint detection technology based on sound intensity threshold, and sound source localization technology based on Stabilized Fast Transversal Recursive Least Square (SFTRLS) algorithm and microphone array model are used. Experimental result shows that even under the condition of low SNR, the muzzle blast wave endpoint detection technology and the sound source localization technology can still achieve a high accuracy on a small microphone array.
