Buried Target Detection Using Time-Reversed Acoustics

Abstract

In the spring of 2000, a proposal was submitted to Mr. Ken Dial at the Office of Naval Research (ONR) to study a novel approach of time-reversed acoustics to detect targets buried in a littoral environment. The proposal was written by Dr. Thomas Drake, currently at ONR, and David Pierson, currently at John Hopkins University Applied Physics Laboratory (APL), under the advice of Dr. Tony Clark, currently at North Carolina State University (NCSU), and completed under the guidance of Dr. David Aspnes, also currently at NCSU. The research demonstrated through theoretical calculations and computer simulations that time-reversed acoustics can be used to detect and classify a target buried in a inhomogeneous environment using an acoustic transceiver of simple geometry.
