Title: Time-frequency analysis applied to signaturing of underwater acoustic signals
Author: Boashash, Boualem; O'Shea, Peter
Abstract: The Wigner-Ville distribution (WVD) and the cross Wigner-Ville distribution (XWVD) are applied to signal detection and classification, and signal-to-noise ratio (SNR) performance is discussed. The method is applied to signaturing the individual cylinders of a diesel engine. A comparison with the short-time Fourier transform is provided.
Description: This paper reports preliminary work of an earlier application of time-frequency techniques to a real-life application. A software package that calculates IF estimates and TFDs can be downloaded from the web site: www.time-frequency.net
