Abstract:

Current methods to extract information about the ocean surface wave field from radar measurements primarily rely on use of Fourier transforms FFT and filtering spectra on the linear dispersion relationship for ocean surface waves. This report discusses development and evaluation of the use of proper orthogonal decomposition POD as an alternative method. Results show similar performance of conventional FFT-based techniques and POD methods for estimation of wave statistics however, evaluations show improved performance of the POD method for phase-resolved wave fields, particularly for wave fields with high energy off the linear dispersion relationship
