Wavelet ridge diagnosis of time-varying elliptical signals with application to an oceanic eddy
Wavelet ridge diagnosis time-varying elliptical signals oceanic eddy
2009/11/9
A method for diagnosing the physical properties of a time-varying ellipse is presented. This essentially involves extending the notion of instantaneous frequency to the bivariate case. New complicatio...
Classifying ships by their acoustic signals with a cross-bispectrum algorithm and a radial basis function neural network
acoustic vector signal cross-bispectrum feature extraction RBFNN ship classification
2011/9/9
An algorithm for estimating the cross-bispectrum of an acoustic vector signal was formulated. Composed features of sound pressure and acoustic vector signals are extracted by the proposed algorithm an...

Wind-Driven Ocean Surface Infrared Signals
2008/12/30
In the course of archiving positions of the edge of the Loop Current from satellite infrared (IR) data, we have found a substantial amount of energy at periods in the “wind-driven band.” Using a techn...
