Abstract
Experimental result of velocity measuring technique, namely, The ultrasonic Doppler, the technique employs a phase shift oscillator to be combination of signals for mixer replacement and tracks the Doppler frequency, is reported. The received ultrasonic signal was fed to the phase shift oscillator that generate 40.7 kHz of natural frequency as same as transmitted frequency. An output response of received ultrasonic present evidently in Doppler frequency which is proportional to velocity of object. Additionally, The great advantage of the multi-time technique could be used in order to predict its behavior. Measurement results verify the efficacy and agree well with analysis.
