摘要

The long-period gravity wave, the wave period from some tens seconds to some minutes, induces not only the big sway of a ship moored and berthed in the harbor due to the horizontal long-distance motion of a water particle but also strong exfoliated flow and vortices near the harbor entrance. They cause serious problems on the safety navigation of vessels entering and leaving the harbor, however this gravity wave has not been researched sufficiently. Then it is quite important to reveal the characteristics of this long-penod gravity wave and to solve various problems induced by this wave. In this paper, the kinematic GPS long-period gravity wave measurement system with arrayed buoys is proposed. As the result of this simulation, the half power width in the estimated direction by the MUSIC spectrum method has only the width of 0.5 degree. The propagational wave direction can be estimated precisely enough.
