Abstract(in English) We have developed a technique for measuring both the axial and transverse components of displacement and velocity with a single beam by a time-domain correlation technique. Our method is based on the calculation of a cross-correlation between RF echo signals taken at a certain repetition rate. An axial component can be determined from a time shift in the peak value of the correlation. A transverse component can also be obtained from the peak value of the correlation that decreases at a certain rate, depending on the magnitude of the transverse component. In this research, we have studied the accuracy of our method by using computer simulation and basic experiments. From the results, the maximum errors for velocities and displacements were about 10% and the errors for beam angles were less than 3 degrees.
