Acoustic Identification of Filler Materials in Unexploded Ordnance
Abstract
The objective of this project is to utilize acoustic waves to identify the materials inside sealed unexploded ordnance (UXO). Acoustic waves are high frequency pressure fluctuations (sound) that travel through materials. Small sensors clamped to the outside of the ordnance send low-energy acoustic waves through the container walls and filler. The received signals are analyzed to determine the characteristic acoustic properties of the filler material. To identify the filler, these measured properties are compared to a database of properties for known explosive and inert filler materials. A device based on this acoustic technique would permit personnel to quickly identify common inert UXO items, and optimize subsequent verification. Significant cost savings can be achieved through more efficient and safer clean-up procedures and the reduction of blow in place remediation procedures. Currently, 75 % of the costs associated with cleanup of UXO contaminated sites are derived from remediating non-hazardous items.
