摘要：
The study described was conducted to evaluate numerous geophysical techniques to determine their applicability to the detection of clandestine tunneling activity, either in progress or completed, which is directed against field fortifications. The first priority was to develop a rapid and reliable approach for detecting tunneling at shallow depths (less than 50 m) in rock.
