The purpose of these labs are to provide a comprehensive overview of all the technical aspects in acoustical sensing and imaging. The coverage includes system modeling, resolution analysis, signal processing, error reduction, resolution enhancement, and motion estimation, with results from full-scale field experiments and applications. The technical details are elaborated on "Acoustical Sensing and Imaging" by Hua Lee.
