Seismic and Acoustic Vibration Imaging (SAVi)

Program Manager: Dr. Monte Turner

The goal of SAVi is to develop and demonstrate a mobile vibration imaging system that can conduct remote measurements of ground vibrations generated by active seismic or acoustic sources. These measurements shall be processed to detect and locate near-surface tunnels and landmines. The system will provide high-confidence target detection and discrimination under a variety of environmental conditions in the presence of natural and man-made clutter.

In brief, the objectives of the SAVi program are to:

• Develop an integrated, laser vibrometry system to detect seismic wave anomalies caused by near-surface tunnels and acoustic resonances indicative of anti-personnel and anti-tank mines
• Develop the components necessary to support such a system, including focal plane arrays (FPAs), lasers, active seismic & acoustic excitation sources, and detailed data processing and throughput capabilities.
• Support stationary and mobile operations for precision characterization and high area-rate search modes for tunnels and landmines.
• Provide near real-time detection with High PD and Low PFA for both tunnels and landmine detection in cluttered environments.
