A transient suppression method for piezoelectric ceramic transducer is presented. By adding some special pedestal pulses to the original transmitted signal,the transient effects in the output of the transducer can be just precisely canceled,thereby achieving the broadband transmission by use of a narrowband transducer.The experimental results show that the transient responses of the sinusoid pulses and coded signals are suppressed successfully and the acoustic waveforms radiated into the surrounding water are improved significantly.
