Abstract

In this paper, we derive analytical formulas for the coherence length of a spherical wave propagating in oceanic turbulence based on the theory of second moments and power spectrum of homogeneous isotropic oceanic water. By equating the spherical wave coherence length solutions in oceanic and atmospheric turbulence, we express oceanic turbulence parameters using an equivalent structure constant employed in turbulent atmosphere. Our results provide a convenient analytical and numerical tool for analyzing beam propagation problems in oceanic turbulence and improve the theoretical basis for applications.
