Abstract
<p> Modeling various global environments requires accurate calculations of air-sea momentum transfer. However, the accuracy of field measurements affects some parameters of the calculation formula, such as the drag coefficient. Therefore, a high-precision and high-frequency measurement method that can measure wind speed and wave conditions simultaneously is needed. In this research, we propose a method for estimating wave conditions (wave period, wave height, and wave direction) using the motion of the small-buoy which is designed to synchronize with the waves. Proposed method is able to reduce sensor error and integration error by sensor fusion of two IMU sensors based on geometric constraint of buoy motion. A windwave tank experiment shows that the proposed method can accurately estimate wave conditions.</p>
