Note on Iterative Methods for calculating Directional Spectra

Abstract:

There have appeared in the literature iteration schemes for improving the resolution of Maximum Likelihood estimates of directional spectra from heave/pitch/roll wave buoy data. In this note we provide illustrations showing,that when iteration schemes with a firmer foundation are used, the iteration converges to spectra very closely resembling Maximum Entropy spectra. Comparisons between Maximum Entropy and iterated Eigenvector spectra are also made.
