1. A method of computing wavenumber-frequency spectra comprising:

  • computing a position vector from signal data received from each sensor in an array of sensors based on the sensor coordinate position on a surface defined by said array, in three orthogonal directions;

    performing a Fourier transform on time data from each said sensor;

    performing a spatial Fourier transform based in part on each said position vector.
