Abstract

The objective of this study is to justify the use of the Hilbert Transform, i.e., the Orbital Method, on analysis of wave statistics obtained from field data and simulated data. The results were also compared to those analyzed by the zero-up-crossing method and the modified zero-up-crossing method (Thompsom, 1984). It showed that wave statistical characteristics calculated with the orbital discretion criterion are more consistent in different spectral width conditions than those with the other two methods. The results may suggest that the orbital method is a more proper wave discretion criterion than the (modified) zero-up-crossing method.
