Abstract

Active acoustic detection of unmanned underwater vehicle (UUV) remains challenging because of weak target echoes in backward scenarios. In this paper, a real-time forward detection method using limited target data was proposed. Trained dimensionality reduction technique was employed to suppress dominant direct blast interference. A novel sonar system was developed based on detecting target-induced variations in the transmitted acoustic field. High-frequency underwater acoustic barriers were established by deploying multiple source and receiver buoys with proposed method embedded. Remote sensing was realized through satellite communication and post-processing. A sea trial was conducted to evaluate the system performance. The timing of each crossing event was clearly observed, and target range was further estimated through data fusion. The system performance was found to be influenced by the channel and the source-target-receiver geometry. The effects of ambient noise and direct blast interference were comparatively analyzed.

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
