A New Approach to Target/Interface Detection in the Presence of Noise

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 or interfaces within the medium.  The 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.
