基于联合神经网络的水声目标识别方法

Underwater acoustic target recognition method based on joint neural network

为了改善传统的单一识别网络难以充分考虑水下声音样本各方面特征的缺陷,本文利用联合一维卷积神经网络与长短期记忆网络2种网络串行的方式,构建一种新的网络框架,首次将联合网络运用到水声目标识别中。其次,用船舶音频数据作为数据集输入网络,对网络性能进行评价,进行识别结果的可视化分析。通过结果分析得出,该网络能够实现对水声目标的识别分类,与单一神经网络相比,联合网络的识别精度更高,正确率等相关指标均优于单一识别网络,为水声目标识别领域的深度学习发展提供了新的参考方向。

In order to improve the defect that the traditional single recognition network is difficult to fully consider all features of underwater sound samples,this paper uses the joint one-dimensional convolutional neural network and long shortterm memory network to construct a new network framework,and applies the joint network to underwater acoustic target recognition for the first time.Secondly,the ship audio data is used as the data set to input the network,and evaluate the network performance,and the visual analysis of the identification results is carried out.The interpretation of result shows that this method can realize the recognition and classification of underwater acoustic target.Compared with the single neural network,the recognition accuracy of the joint network is higher,and the relevant indexes such as the accuracy are better than that of the single neural network,which provides a new reference direction for the application of deep learning in the field of underwater acoustic target recognition.
