Local Materials Characterization Given Only Single-Sided Access
In many remote-sensing applications, propagating waves are introduced into a medium and the echo response from the medium is analyzed in order to characterize the medium. The goal of this project is to further develop a new measurement and data analysis approach for the local characterization of a medium based on backscattered signals (that is, returns echoes from within the medium). The new approach does not require known wave propagation distance, beam modeling, or known wave speed. The technique involves a new scheme for avoiding the influence of the remote sensing measurement system.
