Abstract

A formula is developed in this paper to calculate array gain when the plane-wave assumption is not applied. The formula is developped based on the assumption that the noise in the deep water is Gassian white and isotropic. The performance of a vertical linear is analyzed in the range-independent ocean, and also in a weak range-dependent ocean perturbed by random internal waves. Simulation results illustrate that the array gain is influenced by signal and environment features in the real ocean, and the array gain cannot keep increasing with the increasing of element numbers. It should be tested and simulated to decide the array length and the number of array elements.
