Abstract

A method for estimating the directional spectrum as well as the reflection coefficient in a incident and reflected random wave field is developed for practical use. In the method, the directional spectrum is assumed to be expressed by a circular normal distribution which includes three parameters. Then the parameters are estimated by the maximum likelihood method. The present method is applied to laboratory data, and the parameters are estimated for two kinds of wave gauge arrays. A measure of accuracy of the estimated parameters is also proposed.
