Abstract : An investigation of the applicability of the Jacobi Function orthogonal polynomial representation of the impulse response function for the determination of ship motion from towing tank tests with irregular waves has been initiated. An analysis of the inverse Fourier transformability of the frequency domain gain and phase information obtained in lieu of time domain impulse response function is given with observations of areas of fallibility and recommendations on circumventive methods.
