Distributed Mobile Device Based Shooter Detection Simulation.

摘要

In this report we develop a system for simulating shooter detection under varying system parameters and configurations. First, we discuss the mathematical details of the shooter detection problem. Next, we detail the simulation software that we developed to enable these analyses. We go on to study the performance of the system under various forms of error, including microphone localization error, inter-microphone clock synchronization error, and microphone count and configuration. Analysis is performed to determine, for many different configurations of these system variables, the ability to locate the shooter, as well as the accuracy of the computed location. Finally, we summarize the findings and make recommendations for future system design.
