Noise reduction optimization method and noise reduction system for anechoic tile of underwater vehicle

The invention relates to the technical field of underwater vehicle noise reduction, and provides an underwater vehicle anechoic tile noise reduction optimization method and a noise reduction system, and the method comprises the following steps: S1, collecting training vibration noise data of an underwater vehicle in different operation environments, and training sonar noise data sent by the underwater vehicle; s2, randomly dividing the training vibration noise data and the training sonar noise data into equal time periods as a training data set; and S3, constructing a time-space attention mechanism sequential network model, and inputting the training data set into a time-space attention mechanism sequential network to obtain predicted noise data. According to the noise reduction optimization method and the noise reduction system for the anechoic tile of the underwater vehicle, through setting a time-space attention mechanism sequential network model, the shell noise and external sonar information of the under
