| 摘 要： | 多频海底声学原位测试系统是国家海洋局第二海洋研究所自行研制的海底声学原位测试系统。利用声源换能器的等效电路，分析了声源换能器输入终端输入脉冲与输出接收脉冲之间的关系。将系统的低频声源等效为一定半径的球形声源，确定了系统在15kHz时在试验海域海水中的声源换能器的角频率响应和输出回路品质因子。计算了系统理论接收脉冲，结果表明输出接收脉冲并非输入脉冲的简单复制。并与实测接收脉冲进行了比对，理论接受脉冲与实测脉冲在细节上达到了很好的匹配，说明本文确定的各响应参数很好的代表了本系统在海水中的声源响应。 |

| Abstract: | Multi-frequency in situ sediment seabed acoustic measurement system is produced by Second Institute of Oceanography, SOA. Utilizing the equivalent circuit of source transducer, analyze the relation between the input pulse and the out pulse of the source transducer. Equal the low frequency source to spherical source with some radius and confirm the resonance angular frequency and the quality factor of the output circus of the transducer with 15 kHz frequency in seawater. Calculate the theoretical received output pulse and the result indicate that the output pulse is not a replica of the input pulse. And compare the theoretical pulse and the practical pulse and find they match perfect in detail. And this indicates that the parameters of the source resonance the paper ensured represent the source resonance of the system very well. |
| Keywords: | situ acoustic measurement source resonance transducer pulse wavelet |
