Abstract

The ocean wave information is indispensable to study the ocean environment and also important for safety and economical ship navigation. Remote sensing technology using a satellite image is the useful way to measure it. This technology isn't accurate to know the more detailed information around a small area, for example, fishing port, etc. It is suitable for getting the average information of the large area.<BR>The projected light distribution method was kept proceeding to measure the detailed wave height distribution of the limited part. But, it's very difficult to exceed a laboratory scale.<BR>This paper presents the way to measure the unsteady wave height distributions using the wave surface inclination distributions. The wave surface inclination distributions are analyzed the movement of images random pattern. (e.g. cloud images) An unsteady wave height distribution is measured by this method and compared with the results measured by super-sonic wave height meters. The results show good agreement between them.
