摘要： PROBLEM TO BE SOLVED: To solve problems, in wave height/direction measurement by a GPS buoy, wherein correct measurement cannot be made, since the motion of water particles do not match that of the buoy, that a wave direction cannot be measured by the covariance of the horizontal position and the vertical position of the buoy, and that neither the wave heights nor the wave directions are measured for each frequency band.
SOLUTION: The first problem is solved by a method of making a signal to pass a digital filter for removing a motion component, in a frequency region where there is some difference in the position between the water particle and the buoy, and a method of correcting the difference in the position between the buoy and the water particle by a digital filter. The second problem is solved by a method of differentiating the horizontal position, finding the horizontal speed, and finding the covariance of the horizontal speed and the vertical position. The third method is solved by a method of making the positional data of the buoy or the estimated position data of the water particles to pass a digital filter, such as a band-pass filter and classifying them into each period range beforehand, and performing the aforementioned processings.

摘要： PROBLEM TO BE SOLVED: To avoid a surface conversion from hydraulic wave with poor accuracy which occasionally appears by converting a hydraulic wave with large wave height to a surface wave by use of a surface wave conversion digital filter to determine the wave height, since an ultrasonic system cannot be generally used for high wave height because of breaking of waves. SOLUTION: A wave height is generally calculated by processing data for 20 minutes. Even if wave breakage occurs for the 20 minutes, a point where ultrasonic waveform is normally measured is present. The characteristic of the surface wave conversion filter is determined so that the waveform with the normal ultrasonic wave form is matched to a surface wave obtained by conversion from a hydraulic wave, and the hydraulic wave is converted to the surface wave by use of the determined digital filter.
