Gunshot Detection System for JTRS Radios

Free registration required

Executive Summary

This paper presents a novel solution for detecting and locating gunshots using minimal equipment on a JTRS radio is proposed. Each radio acts as a sensor node to determine and share muzzle blast time of arrival information in order to determine a shooter location. The feasibility of such a system was investigated by developing detection and location algorithms and testing each algorithm's effectiveness in both simulation and with real data. The detection algorithm is used to accurately pinpoint the arrival of the muzzle blast of a gunshot at a single microphone and was realized using a rake-correlation filter loop.
