Estimation of Directional Spectra by ML/ME-Methods

by Ola Haug, Oceanor A/S, Trondheim, Norway,
Harald E. Krogstad, Oceanor A/S, Trondheim, Norway,



Document Type: Proceeding Paper

Part of: Ocean Wave Measurement and Analysis

Abstract:

The paper discusses the statistical Maximum Likelihood (ML) and Entropy (ME) methods for estimation of directional wave spectra. A combined ML/ME method is derived, and a reduced version is shown to have superior properties compared to the Capon ML-method and the Iterative ML-method.
