Abstract : The Office of Naval Research issued Grant N00014-02-1-0346 for Optical Measurements of Ground Vibrations to the National Center for Physical Acoustics at the University of Mississippi. The University of Mississippi is involved in an applied research program to develop an acoustic technique to detect buried landmines. In this technique, the ground is excited using acoustic or seismic sources which elicit resonance in buried mines. This resonance causes increased amplitude in the ground vibration over the buried object. The primary methods of measuring ground vibration involve laser Doppler vibrometry and tend to limit operational tempo due to long scanning times and be adversely affected by loose ground cover. Research has been performed to develop a Doppler acoustic technique for the measurement of ground vibration. Initial laboratory and field tests indicate this device has significant promise for overcoming the current limitations.
