摘要

A new method of measuring complete vector components of targetnvelocity is proposed. This method makes it possible to measure targetnvelocity components both along and transverse to the beam axis in twonsteps. The first step is Fourier transformation of the received signalsnin the direction of the time-axis (the ultrasonic pulse emissionnnumber). The second step is projection integration in the polar-axisndirection. These two steps provide the two velocity components along andntransverse to the beam axis. The new method is similar to the ComputednVelocimetry method (CV) proposed previously by the authors, except thatnit does not require Fourier transformation in the polar-axis direction.nThe theory for this method and results of numerical simulation arenpresented
