Patent Number: 6415666
Title:  Method and apparatus for acoustic detection of mines and other buried man-made objects
Inventors: Dimitri M. Donskoy, Alexander M. Sutin
Abstract: In order to detect buried compliant objects such as land mines and pipes, an acoustic signal is directed into the ground to excite vibration of a buried compliant object. A probing signal is also directed into the ground toward the vibrating object, and the probing signal is modulated and reflected by the vibrating object. The modulated, reflected probing signal is processed to determine therefrom the presence of the buried compliant object.
