Abstract
According to the problems of underwater target signal was susceptible to noise and the signal-noise separation was difficult and so on, an underwater acoustic signal noisereduction method based on LCD and ICA was proposed, of which 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 reduce the noise interference and improve the reliability of target detection.关键词
