Extraction method of weak underwater acoustic signal based on the combination of wavelet transform and empirical mode decomposition
When studying underwater acoustic exploration, tracking and positioning, the target signals collected by hydrophones are often submerged in strong intermittent noise and environmental noise. In this paper, an algorithm that combines empirical mode decomposition and wavelet transform is proposed to a...
