Paper Abstract

A method for the detection and localization of personnel using seismic sensors is described. This particular application of seismic signal processing is different from typical applications involving earthquakes or sonic well-logging, and thus requires the development of new techniques. The proposed approach consists of a matched filter-based detection algorithm, time of arrival association of detected footsteps from different sensors, and localization using a hyperbolic location estimator. This method was tested using data collected in southern New Hampshire from four vertical-axis geophones. The speed of sound at the test site was estimated using an impulsive source. Footsteps were reliably detected at ranges up to 30m. Localization errors were found to vary linearly with range, with an average estimation error of 8.4 m observed. With improvements in the sensitivity of the seismic sensors, this approach will yield reasonable position estimates of personnel for use in a tracking algorithm.
