Multiple Backscattered-Noise Reduction with Applications to Imaging and Target/Interface Detection

In many remote-sensing applications, propagating waves are introduced into a medium and the echo response from the medium is analyzed in order to detect individual targets.  In certain cases, echoes from additional echo sources distributed over the echo volume interfere with the detection of the response from the target.  In ultrasonic nondestructive evaluation, for example, the target may be a crack in a component with the noise generated by echoes from the inherent structure within the material.  The goal of this project is to reduce to practice and establish the range of applicability of a multiple scattering noise reduction scheme that was noticed by at MU by Dr. Neal.  The approach is applicable to both acoustic and electromagnetic wave scattering problems.
