An Estimation of Ocean Wave Characteristics Based on Measured Ship Motions
Journal of the Society of Naval Architects of Japan
It is known that a ship can be regarded as a type of wave measuring device, and under the assumption of linear superposition, wave spectra can thus be estimated from measured spectra of ship motions. Based on this idea, the evaluation of one-dimensional wave spectra, as well as directional wave spectra, has been extensively carried out in recent years. However, when a ship is traveling with an advance speed in following seas, there is a range of encounter frequencies We for which cannot bedoi:10.2534/jjasnaoe1968.1998.184_159 fatcat:glw7dofskfgsbir5pnl47iv5xy
