The Resolution of Directional Wave Spectra Using the Maximum Likelihood Method.

Abstract

The Maximum Likelihood Method is examined for use in measuring the directionality of ocean wave spectra in conjunction with sparse wave-gage arrays. Directional characteristics of small wave-gage arrays and the effects of noise, wavelength, and gage spacing are analyzed via simulated input spectra. A figure of merit is derived as an aid in array design. (Author)
