Özet

People moving on a ground generate a consecutive impact which excites the ground and vibrations spread as seismic waves expanding from the source. Seismic level vibrations could be used to detect human intruders. In this study, ground vibrations are acquired and analyzed by dividing the time history into windowed segments. In order to collect vibration signal an experimental setup is formed and different scenarios are tested. Then, test results are analyzed in time and frequency domain. Tests are exposed the walking characteristics of human as well as ground vibrations propagation components. Results show that human intrusion can be identified by ground vibration measurement and analysis.
