Mine Classification/Identification by Structural Acoustics

The overall goal of this program was to develop the ability to detect, classify, and identify buried and near-buried mines at far greater ranges, and thus much more rapidly, than is currently possible. This program, which emphasized buried and near-buried mines, was coordinated with the NRL 6.2 base program in MCM. The objective of this program was to exploit low frequency structural acoustic clues which might exist in the scattered acoustic fields from buried and near-buried mines for long range, rapid mine classification and identification. Once these structural acoustic mechanisms and clues were established in the free--field scattering from these mines, the goal was to establish the basic effects on the structural acoustic response of sediment loading and to extend the newly developed classification/identification algorithms based on these clues to the buried/near-buried, sediment-loaded case.
