Urban Seismic Surveillance System

Lack of situational awareness in urban environments is a significant problem. In-city ground assets are vulnerable and airborne assets are expensive and limited. Seismic surveillance using offset arrays offers a solution that is persistent, stealthy, defendable, and relatively inexpensive. Difficulties, though, include detecting anomalous activity within the high levels of background activity and localizing any anomalous activity once detected. The goal of this program is to address these two difficulties through the development of a novel seismic surveillance system that utilizes novel signal processing methods to aid in anomaly detection and uses geophysical modeling to aid in improved array design. During Phase I, we will demonstrate the primary anomaly detection algorithms and propose an array design optimized for this application. This work lays the foundation for a full-scale array to be delivered during Phase II.
