The basic relationship between array parameters and the noise fields are reexamined in order to reconcile the theoretical analysis and experimental measurement of ambient-sea-noise directionality. The derivation of the ambient-noise directionality in terms of measurable quantities is examined in detail, and the limitation of numerical computation is discussed in terms of existing computer algorithms. Comparisons between a simulated noise field and a real noise field obtained from an actual ocean environment are made for a vertical AUTOBUOY directional array.
