Figure 7From: Self-similarity property of acoustic data acquired in shallow water environmentVariance-time plots from CH1–CH4 of the hydrophone line array. The figure shows that in the shallow water environment, acoustic signal of each channel has good self-similarity. The straight line from the upper left zero point to the lower right corner indicates that the slope of a boundary of 0.5. If the variance is located below of the slash, said they did not have the self-similarity, otherwise have self-similarity.Back to article page
