Abstract(in English) | In the standard pulse Doppler method,target velocity is obtained from the Doppler-shift only for the center frequency of the ultrasonic transducer.In this standard method,therefore,the limit of the measurable velocity is not neglected.In this paper,we propose a new method for measuring velocity component higher than the limit of the standard method by obtaining the Doppler-shift from the phase characteristics not for the center frequency but for the frequency band around the center frequency of the ultrasonic transducer.After describing the principle of the method, the principle is comfirmed by the simulation experiments and the experiments using a water tank. |
