声在海洋中的传播是认识所有其他水声现象的基础,因此,声传播的测量和建模是海洋声学研究中的一项基本任务,本文对浅海传播实验数据进行了初步分析;用简正模模型解释了测量的脉冲响应时间稳定性差的原因,同时还对信道系统函数的垂直空间相关性进行了估计与测量,结果表明两者的一致性比较好;另外还比较了模基匹配滤波与常规匹配滤波和基于测量的脉冲响应函数的匹配滤波三种匹配滤波的性能。虽然模基匹配滤波结果不如基于测量的脉冲响应的匹配滤波,却优于常规匹配滤波,这说明对浅海声信道建模是可行且有效的。 Acoustic propagation in the ocean is the basis of understanding all other underwater acoustic phenomena. Therefore, the measurement and modeling of acoustic propagation is a basic task in ocean acoustic research. In this paper, The reasons for the poor stability of the measured impulse response are explained. The vertical spatial correlation of the channel system functions is estimated and measured. The results show that the consistency between the two is good. In addition, Filtering and Matched Filtering Based on Measured Impulse Response Functions Three Matched Filtering Properties. Although the results of modal-based matched filtering are not as good as the matched filtering based on the measured impulse response, it is better than the conventional matched filtering, which shows that it is feasible and effective to model the shallow-sea acoustic channel.
