Field correlation of spherical wave in underwater turbulent medium

Abstract

The absolute field correlation of the spherical wave in an underwater turbulent medium is investigated at the receiver plane by using the extended Huygens-Fresnel principle. Results denote that increase in the propagation distance, the rate of dissipation of the mean squared temperature, and microscale length cause reduction in the absolute field correlation. Field correlation increases when the wavelength and the rate of dissipation of the turbulent kinetic energy and parameters of temperature and salinity contribution to the turbulence decrease. Salinity dominated turbulence corrupts the absolute field correlation much more in comparison to the temperature dominated turbulence. Change in the receiver coordinate is found not to affect the absolute field correlation. (C) 2014 Optical Society of America
