Study of wave group velocity calculation from nonhomogeneous wave field by spatiooral wavelet transform

Research output: Contribution to conferencePaper

Abstract

We here applied spatiooral wavelet transform to calculate wave group velocity from inhomogeneous wave field and discussed its accuracy here. The relationship between wavelet and wave group velocity results was presented. We revealed the practicability of spatiooral wavelet transform in wave field analysis by using different kinds of simulated wave field. According to our analyzing cases, we observed the calculated accuracy is influenced by the frequency resolution from the wave field. At least continuous 64 images with the size of 128pixel×128pixel are capable of obtaining adequate frequency resolution for wave group velocity calculation and getting high accuracy results.
