Abstract

Abstract

Based on numerical simulation and observation data, the four estimating methods of directional spectrum, maximum-likelihood method(MLM), extended eigenvector method(EEV), extended maximum-entropy principle(EMEP) and Bayesian directional method(BDM) are studied about their reliabilities respectively. It is shown that MLM, EEV and BDM basically give the same directional distribution in general. However, BDM holds the best reproducibility in any cases, and is inferior to MLM and EEV in practicality. EMEP is not suitable to real observation data because of its poor stability.
