A NEW METHOD FOR DIRECTIONAL WAVE ANALYSIS BASED ON WAVELETS

摘要

A new method for the estimation of directional spectra is outlined and illustrated with data from an array of wave gauges. The method employs wavelet analysis techniques and thus is well adapted to dealing with non-stationary data. The product of this analysis is the wavenumber directional spectrum, which is of fundamental value to a host of applications of knowledge of the wind-driven ocean surface. Since the basic data are time series from each gauge in the array, frequency direction spectra may also be obtained.
