This paper proposes a used in acoustic signal processing method of doppler log, based on the doppler log signal trans-ducer of high voltage isolation launch and instrument op-amp differential amplification signal processing method, greatly improv-ing the signal-to-noise ratio of the echo signal, late into the signal processing channel, simplifies the processing methods, im-proved the precision of speed, is advantageous to the doppler velocity stability.
