A New Approach for the Reduction of Backscattered Noise with Applications to Imaging and Target/Interface Detection

In remote sensing problems involving acoustic waves or electromagnetic waves, scattering based noise inhibits our ability to detect, image, and characterize targets.  These targets may be flaws in engineering materials, land mines in electromagnetic wave applications, or microcalcifications associated with breast cancer screening.  This project deals with reducing to practice and understanding the range of applicability of a new noise reduction approach discovered at MU by Dr. Neal.  The approach utilizes a new measurement and data analysis scheme using existing equipment.
