Application of time-frequency and time-scale analysis to underwater acoustic transients

Open publisher page 3 citations

Abstract

Side-by-side comparisons of numerous time-frequency and time-scale representations of unclassified acoustic transients are presented. The techniques illustrated include the short-time Fourier transform (STFT) tuned to different analysis bandwidths, the Gabor-wavelet time-scale representation (TSR), the adaptive optimal radially Gaussian kernel (AOK) time-frequency representation (TFR), and model based TFRs. The strengths and weaknesses of the various analysis representations are discussed.>
