A Novel Method for Footstep Detection with an Extremely Low False Alarm Rate

摘要

Development of advanced seismic footstep detection systems for perimeter and zone protection can offer new method for improved homeland security and defense applications. High false alarm rates associated with current seismic security systems has been a formidable obstacle in their widespread adoption. This paper describes a novel method for seismic footstep detection in which false alarms are inhibited and virtually eliminated. In addition, a significant increase in detection range for seismic security systems is also reported. Proprietary software was specifically developed to improve processing of the seismic signals. This software allows one to uniquely analyze over three-dozen signal shape parameters within the detected seismic signal. This novel software enables real time signal analysis, thus effectively offering a more efficient and effective alternative to using trained personnel.
