摘要:
This paper reviews a technique for the generation of broadband acoustic transmissions. Wiener (least‐squares) filtering is applied to the problem of precompensating the transducer driving waveform so that the subsequent acoustic pulse has a broadband nature. Experimental results show that a transducer having two resonance peaks at 9 and 17 kHz, each having bandwidths of about 2.5 kHz, may be compensated to have less than 3.5‐dB ripple in the transmitting frequency response from 7 to 37 kHz.
