Target Tracking by Using Seismic Sensors

(U) Robust Personnel Detection using PIR and Seismic Sensors

In this paper we analyze the signals from passive infrared (PIR) and seismic sensors to detect people. The PIR data analysis is done to determine the radiation source such as a human or an animal based on the signal strength, slopes of the signals, the number of Fresnel lens zones crossed by the target. The seismic data analysis is done to ascertain whether the footsteps belong to a human or an...

Feature Selection and Occupancy Classification Using Seismic Sensors

In this paper†, we consider the problem of indoor surveillance and propose a feature selection scheme for occupancy classification in an indoor environment. The classifier aims to determine whether there is exactly one occupant or more than one occupant. Data are obtained from six seismic sensors (geophones) that are deployed in a typical building hallway. Four proposed features exploit amplitu...

Localization of Subsurface Targets using Optimal Maneuvers of Seismic Sensors

This dissertation is dedicated to my parents, specially to my late father. Thank you for your love, affection and care, in good times and in bad times. And also to rest of my family. Thank you for your love, encouragement, and support. iii ACKNOWLEDGEMENTS It has been a long journey for me in the completion of this thesis. I was helped and influenced by many persons along the way. First of all,...

GFZ Wireless Seismic Array (GFZ-WISE), a Wireless Mesh Network of Seismic Sensors: New Perspectives for Seismic Noise Array Investigations and Site Monitoring

Over the last few years, the analysis of seismic noise recorded by two dimensional arrays has been confirmed to be capable of deriving the subsoil shear-wave velocity structure down to several hundred meters depth. In fact, using just a few minutes of seismic noise recordings and combining this with the well known horizontal-to-vertical method, it has also been shown that it is possible to inve...
