The purpose of this effort was to determine the feasibility of the SECURES System for the Effective Control of URban Environment Security system concept as a reliable and practical means to instantly notify police of gunshot locations in urban environments. This feasibility study involved the acquisition of gunshot and background noise acoustic data, analysis of this data to establish methods of identifying gunshots from the background noises, and an investigation into hardware designs for implementation of these methods into a reliable and economical system. This effort also involved breadboarding and testing critical portions of the electronic circuitry and developing a physical model of the pole unit enclosure. Some of the work presented in this report were supported by internal research and development funding provided by Alliant and some results are considered company proprietary. These include 1 overall SECURES TM system concept 2 formulation of the gunshot discrimination algorithm 3 analog pulse detection circuit design 4 pole unit digital electronics design concept and 5 design and model construction of the pole unit enclosure.
