Research Abstract

The ocean wave is complicated phenomenon in which the irregular wave form various directions overlapped. In this study, the method for measuring such wave by experimental tank was developed. Developed measurement technique carries out the at one time wide area using the ultrasonic wave which spreads in spherical shape. The measurement system was completed. The algorithm for obtaining final data was not completed. The research will be continuously carried out on the basis of this study result.
