Abstract:

This report investigates the problem of detecting tunnels it focuses on the characteristics of the propagating medium and on techniques using compressional seismic P and electromagnetic EM waves propagating between sources and sensors located in boreholes at depths comparable with the tunnel for which one is searching. The interaction of P and EM waves with tunnels and with the surrounding media is studied as are detection methods in a general sense. This work has not looked into the specifics of sources, sensors and ambient noise levels. Author
