As a preliminary investigation into the data processing method by a digital computer for ship model experiments in regular waves, an automatic data-handling technique derived from the Fourier Polynominal has been studied.The authors propose in this paper that amplitudes and phase differences of ship motions and regular waves may be defined as the harmonic components correspond to the mean frequency of the encounter waves. They show also that the proposal is available, when the record is sufficiently long and continuous at the both ends of one, even if a model rums with heavy surge or meets uneven regular waves.They have completed the on-line data processing equipments for the Mitaka No.2 Ship Experiment Tank (400m×18m×8m), and made the computer program by which amplitudes and phase differences of ship motions and regular waves are automatically obtained from the records on the magnetic tape of digital type.
