Abstract
How to locate accurately positioning of underwater noise source is the most important link of underwater vehicle fault detection and diagnosis. In this paper, Near-field Acoustic Holography technique is applied to detection and location of noise sources of underwater vehicle, to collect radiated noise information of noise source. A LABVIEW-based underwater vehicle sound pressure measurement system is designed, which has capacity to detect and locate noise sources of the underwater vehicle, so that the fault positioning of underwater target can be located and excluded easily.
