Abstract
Underwater Acoustic Target Recognition (UATR) remains one of the most challenging tasks in underwater signal processing due to the lack of labeled data acquisition, the impact of the time-space varying intrinsic characteristics, and the interference from other noise sources. To achieve state-of-the-art accuracy, we propose a novel classification method by using the fusion features and a 18-layer Residual Network (ResNet18). The recognition experiments are conducted on the ship-radiated noise dataset named ShipsEar from a real environment, and the accuracy results of 0.943 show that the proposed method is effective for underwater acoustic recognition problems and outperforms other classification methods.
