Abstract:

According to the problems of underwater target signal was susceptible to noise and the signal-noise separationwas difficult and so on, an underwater acoustic signal noisereduction method based on LCD and ICA was proposed, ofwhich principle, and method in the field of underwater acoustic denoising were presented. The effectiveness of the pro.posed method was verified by the simulaiton signal. The results showed that the proposed method could effectively reducethe noise interference and improve the reliability of target detection.
