讨论换能器带宽对声脉冲响应谱特征的影响,实验结果表明,窄带频谱出现旁瓣;宽带频谱低端下降,结果与理论分析一致。
The effect of transducer bandwidth on the acoustic impulse response spectrum characteristics is discussed. The experimental results show that the narrow band spectrum has side lobes and the low band width spectrum decreases. The result is consistent with the theoretical analysis.
