Abstract
A simplified estimation of the height and the period of waves generated by a small ship was proposed in previous papers. The estimated heights and periods of waves were in good agreement with the experimental results obtained from a small ship. In this paper, the new system called MUSIC (Multiple Signal Classification) was proposed for analyzing the direction of ship waves. The distribution of directional spectrum of ship waves estimated by MUSIC presented a sharper monotone peak, and the estimated results were supported by field results obtained from a small ship. The proposed estimation of the wave direction of ship waves by MUSIC was confirmed to be very effective.
