Title Shooter Localization using Soldier-Worn Gunfire Detection Systems.
Publication Date Jul 2011
Media Count 9p
Personal Author J. George L. M. Kaplan
Abstract This paper considers the problem of shooter localization using a network of soldier-worn gunfire detection systems. Proposed scheme utilizes the benefits of sensor network layout of all the sensors within a small combat unit to help refine localization accuracy. If the soldier is within the field of view of the shockwave, then using the acoustic phenomena analysis of small-arms fire, the gunfire detection system can localize the source of the incoming fire and the bullet's trajectory with respect to the sensor location. These individual solutions, usually in the form of a bearing and range relative to the soldier, are then relayed to the central node. At the central node level, the individual solutions are fused along with the GPS locations on the soldiers to yield a highly accurate geo-rectified solution.
