Acoustic-to-seismic coupling and detection of landmines

Reviews the physics of acoustic-to-seismic coupling in air-filled solids relating to acoustic technology for mine detection. The measurement technique of mine detection using acoustic-to-seismic coupling has been outlined, Taking advantage of a noncontact, remote sensor, recent measurements using a scanning laser Doppler Vibrometer and data analysis techniques for mine detection are discussed. In the next research and development phase, efforts will be made to develop the current technique into a vehicle-mounted field device. To facilitate this, research is being conducted to increase the speed of scanning and to automatically recognize targets
