Ultrasound is an emerging method employed for nondestructive                    evaluation.  One potential advantage of ultrasound is that the motion           of an object can be detected by observing the frequency shift of the            returned signal.  This research will seek to exploit this advantage by          developing procedures to measure motion parameters with reflected               ultrasound signals and by determining their limitations.  A wide range          of motion types are considered, from determining the motion parameters          of a single moving point reflector through characterizing the motion            of a collection of random reflectors.  The procedures involve                   analysis, simulation and experiments.  The fundamental limitations are          due to the speed of sound, the limited size of the apertures, and the           presence of noise.  The impact of these limitations will be                     investigated by considering the placement of multiple transducers and           novel signal processing procedures.  This should allow translation of           these physical limitations into bounds on the accuracy that can be              applied to practical instruments.  The result of this research will             enhance the understanding of probing media with acoustic signals and            determine the feasibility of a new generation of measuring                      instrumentation.
