摘要
低频换能器的宽带发射是现代水声发展的方向,也是水声技术的一个难点。为了实现低频换能器高保真的发射宽带信号,该文讨论了使用退火算法设计换能器与功放之间的均衡电路,并将其付诸于实验。实验结果表明,我们的方法将声发射的带宽拓展将近3倍,在实际工作中是可行的。
Low frequency and wide band transducer is the trend of development of underwater acoustics. To improve the fidelity of low frequency tansducer, this paper presents designing equalizers by virtue of simulated annealing algorithm between transducers and amplifiers. The method has been carried into execution. The experiments show our method improve the bandwidth of the projector about three times which has been proved feasible.
